Don't Get Attached

Imagine you save your pocket money for a whole year and finally buy a fancy remote-control car. On day one it zooms beautifully. But by day thirty it has started to break. A wheel wobbles, then the battery dies, then the remote stops working. The shop says a repair will cost more than a brand-new car. Any calm person would say, "Sell the broken bits, buy the new car." But you can't. You love this car. You remember the year of saving, the excitement of unwrapping it, the day it zoomed. So instead you pour more money in - a new wheel, a new battery, a new remote - again and again, always hoping the next repair is the last one. A month later you've spent triple the price of a new car, and it still wobbles.

That feeling - being unable to let go of something because of everything you've already put into it - is one of the most expensive feelings a grown-up with money can have. This chapter is about a famous writer who caught exactly this feeling about a machine, and let it swallow almost everything he owned.

The writer was Mark Twain, the man who wrote Tom Sawyer and Huckleberry Finn. He was one of the most beloved storytellers of his time and made a fortune from his books. And yet he nearly ended his life poor, not because his stories stopped selling, but because he fell in love with a machine - a machine he did not really understand - and could not stop feeding it money. His own experience taught a lesson so useful that I want to unpack it slowly, in our own words, so a young reader can carry it for life: love your family and your friends, but never love a thing you own for money - the moment you love it, you stop seeing it clearly.

Let's slow down and ask why this is such a big deal. After all, loving things is usually lovely. Loving your dog, your bicycle, your grandmother's stories - these make life richer. So why is loving a money thing - a machine, a business, a share you bought - so dangerous?

Because love makes you loyal, and loyalty is the enemy of clear thinking about money. When you love something, three quiet changes happen inside your head, and none of them help you.

First, you start defending it. If a friend says, "That thing looks broken," you don't calmly check - you argue back, because it feels like they insulted you. Second, you remember the good old days instead of looking at today. You keep replaying the moment the car zoomed on day one, so the wobbling on day thirty feels like a temporary hiccup instead of the real, permanent state of things. Third, you count all the money you've already spent as a reason to keep going - "I've put in so much, I can't stop now" - when really the money already spent should count for nothing at all in deciding what to do next.

Grown-ups have a plain name for that last trap: they call it the endowment effect and status-quo bias, which is a fancy way of saying we value a thing more just because it's ours, and we prefer to leave it as it is rather than change. The result is that people hold on to broken investments for years, not because a cool-headed look says "this is still good," but because a warm-hearted feeling says "this is mine, and I remember when it was wonderful."

The escape from all of this is a single, honest question you must be brave enough to ask about anything you own: Knowing everything I know today, would I go out and buy this again, right now, at today's price? If the honest answer is no, then the only reason you're still holding it is love - and love is not a reason to keep money in a bad thing. Twain never asked himself that question about his machine until it was far, far too late.

Here's the part most people get wrong, so let's build it up carefully. The trap doesn't spring shut all at once. It tightens slowly, one "just a little more" at a time, and each step feels perfectly reasonable in the moment.

Picture a staircase going down into a pit. On the first step you put in some money for a promising thing. It doesn't work yet, but the person selling it says, "It's almost ready - one more part and it'll be perfect." So you step down and put in more. Still not working. "So close now," they say. You step down again. Each step, the amount you've sunk gets bigger, and each step, the pain of walking back up and admitting the whole thing was a mistake gets worse. So you keep choosing the next step down, because it feels smaller than the giant climb back. That is exactly how a smart person ends up at the bottom of a very deep pit, having agreed to every single step.

Now hold two ideas side by side, because they are easy to muddle. The money you've already put in is called a sunk cost - it's gone, spent, in the past, and nothing you do now brings it back. The money you're about to put in is a fresh choice - it's still in your pocket, and it's the only money you actually control. The trap is that people let the first thing decide the second. They think, "Because I've already sunk so much, I must keep going." But the honest rule is the opposite: the money you've already spent is gone no matter what you choose next, so it should carry exactly zero weight in deciding whether to spend more - only the future matters, never the past.

The right question at every step is not "How much have I already put in?" It's "Starting from today, is putting in more money the best thing I can do with it - better than every other thing I could do with that same money?" Twain, for years, asked himself the wrong question.

Let me tell you the neutral, factual bones of what happened, so the lesson stands on real ground. (These are simple historical facts, not a comment on anyone's character.)

In the late 1800s, printing was a slow, tricky job. To print a newspaper or a book, workers had to arrange thousands of tiny metal letters by hand, one at a time. It was exhausting and expensive. So there was a real prize waiting for anyone who could build a machine that arranged the letters automatically - much faster than a person. Whoever cracked it would change printing forever.

Mark Twain met an inventor who was building exactly such a machine. It was a beautiful, dazzlingly complicated contraption with thousands of moving parts. Twain watched it work and became convinced it would make him unimaginably rich. He didn't just buy a small share and wait. He kept funding the inventor, month after month, year after year, to keep improving it. Every time the machine broke or needed refinement, more money went in. Twain was earning a lot from his writing, and he steadily fed that money into the machine.

Here is the cruel twist of history. While Twain's machine kept being tinkered with to make it perfect, a different, simpler machine - one made by other people - reached the market first, worked reliably, and won. Twain's dazzling contraption, with all its thousands of parts, never became the thing everyone bought. The years of payments bought a machine that the world had already moved past. By the time it was over, Twain had poured in so much that he was pushed toward bankruptcy - a rich, famous, brilliant man, brought low not by his writing but by a machine he loved and could not stop feeding.

Notice what did not cause the disaster. His books never stopped selling. His talent never faded. The ruin came entirely from one held position he refused to judge coldly - a thing he had married in his heart, and kept paying for out of loyalty to a dream long after a calm outsider would have walked away.

Let's rebuild the same trap with fresh rupees and an Indian family, so you can feel it move. illustrative

Meet Rohan, who runs a small printing shop in Pune. He has ₹8,00,000 saved. A clever local engineer shows him a new printing machine he's inventing - one that promises to print twice as fast as anything in the market. Rohan is thrilled. He can already picture his shop becoming the fastest in the city. He puts in ₹2,00,000 to help finish the machine.

Six months later the machine still jams every few pages. The engineer says, "It's the gears - one more upgrade and it's perfect." Rohan, remembering how amazing it looked in the demo, puts in another ₹2,50,000. Another six months: now it's the ink system. "So close," says the engineer. Rohan pays ₹2,00,000 more. By now he's put in ₹6,50,000 - most of his savings - and the machine still can't run a full day without breaking.

Then Rohan hears the gut-punch: a big company has just launched a reliable fast printer, already selling in shops, working out of the box. His half-finished machine is now chasing something the world already has. A calm friend asks him the only question that matters: "Rohan, forget the ₹6,50,000 you've already spent - that's gone whatever you do. Starting from today, would you spend a fresh ₹1,50,000 on finishing this machine, when a working one already exists?" Said that way, the answer is obviously no. But for months Rohan couldn't ask it, because the ₹6,50,000 already sunk was screaming, "Don't let me have been wasted!" That scream is the trap. The ₹6,50,000 was wasted the moment the better machine arrived; throwing in ₹1,50,000 more only makes it ₹8,00,000 wasted.

The trap doesn't only happen with machines. It happens most often with shares, quietly, in ordinary households. illustrative

Meet Aayra, a careful saver. Years ago she bought shares in a company that made landline telephone equipment, paying ₹500 per share for 400 shares - ₹2,00,000 in all. For a while it did well and she felt proud. But then the world changed: everyone moved to mobile phones, and the company's landline business slowly withered. The share drifted down to ₹300, then ₹200, then ₹120.

Every year Aayra told herself the same three things. "I bought it at ₹500, so it must come back to ₹500." "I remember when it was a great company." "I've held it so long, it would be silly to sell now." Do you see all three love-traps at once? She's anchored to the price she paid (which the market does not care about), she's remembering the past instead of judging the present, and she's treating the years she's held it as a reason to hold longer. Not one of those is a fact about the company's future.

A cool-headed advisor asks her the honest question: "Aayra, if you had ₹48,000 in cash today - that's what your 400 shares are worth now at ₹120 - would you go and buy this landline company fresh, knowing landlines are fading?" She admits at once: never. She'd put that ₹48,000 into something with a future. And that admission is the whole answer - because if she wouldn't buy it today, then holding it is the same decision as buying it today. Holding is just buying it again, every single morning, with money she could move elsewhere. The ₹500 she paid long ago is a sunk cost; it should weigh nothing. What weighs everything is: from here, is this the best home for ₹48,000? It isn't. Her love for the old, proud company is the only thing keeping her money trapped in its slow decline.

Here's a third one, because this trap loves to hide inside things that sound modern and exciting. illustrative

Meet Arjun, who runs a successful vegetable-supply business and understands it inside out - margins, spoilage, transport, everything. One day a smooth young founder pitches him a "revolutionary" app that uses complicated technology Arjun has never studied. The founder throws around words Arjun doesn't really follow, but the confidence is dazzling and the promised riches are huge. Arjun puts in ₹3,00,000.

Here's the problem: because the app is far outside Arjun's circle, he has no way to check whether it's actually going well. When the founder says "we just need more money to reach the next milestone," Arjun can't tell if that's true progress or a polite way of saying "it isn't working." Inside his vegetable business he'd know in a heartbeat; here he's blind. So he does the only thing a blind, hopeful person can do - he trusts his feelings and the founder's story. Six months later: ₹2,00,000 more. Six months after that, another ₹1,50,000, because "we're so close, and you've already backed us so far." Both traps are now working on him at once - he's outside his circle and he's chasing sunk costs.

The friend's rescue question comes in two parts this time. First, the circle part: "Arjun, can you actually judge this app on its own merits, the way you judge a vegetable route - or are you just trusting the founder because it sounds impressive?" Arjun admits he can't judge it at all. Second, the sunk-cost part: "Then forget the ₹6,50,000 you've already put in - it's gone either way. Would you hand a fresh ₹1,50,000 to a thing you can't judge, run by a story you can't check?" Put plainly, no. The lesson lands twice: he never had the tools to judge this, and the money already spent was pulling him in deeper precisely because he couldn't see clearly. Had he simply said at the start, "This is outside what I understand, so I'll risk only ₹20,000 I can happily lose, or nothing at all," the whole slow bleed would never have begun.

Let's turn all this into a tool you can actually use, because the lesson is worthless if it stays a story. When you own something for money - a share, a business, a machine, a plan - and it starts to disappoint, there are two questions that break the spell of love. Learn them by heart.

The first is the fresh-eyes question: "Knowing what I know today, would I buy this again right now, at today's price?" If yes, keep it - you're holding for a real reason, not a feeling. If no, then you're only holding out of loyalty, and loyalty is not a plan. This question does something magical: it deletes the past. It doesn't ask what you paid, how long you've held, or how it felt on the good days. It asks only about the future, which is the only thing your next rupee can touch.

The second is the forget-the-past question: "If I ignore every rupee I've already spent, is spending more the best use of my next rupee?" This one directly disarms the sunk-cost scream. Whenever you catch yourself saying "but I've already put in so much," that's the exact moment to stop and ask this. The more you've already sunk, the louder the trap gets - and the more important it is to answer coldly.

Both questions do the same deep thing: they force your eyes off the history and onto the future. That single shift - judging a holding by where it's going, not by where you've been with it - is the whole cure. Everything else in this chapter is just a reason to believe it.

There's a small habit that makes these questions much easier to actually ask, and it's worth building young. Every so often - say, once a year - pretend for a moment that you sold everything you own and it all turned into plain cash sitting in your hand. Now look at each thing you used to own and ask: would I buy it back? The ones you'd happily buy back, you keep. The ones you'd never repurchase, you were only holding out of habit or love, and it's time to let them go. This little game is powerful because it wipes the slate clean of the price you paid and the years you held. It puts you back at the very start, seeing each thing with fresh eyes, exactly the way a calm stranger would. A stranger doesn't love your landline shares or your half-built machine. A stranger just asks, "Is this a good place for money, starting today?" - and that stranger is almost always right.

There's a quieter part of Twain's disaster that's just as important, and it's easy to miss under the drama of the sunk costs. Twain was a genius at words. He was not an engineer. He could not truly judge whether a machine with thousands of delicate parts would ever work reliably, or whether a simpler design would beat it. He was betting big on something that sat far outside what he actually understood.

Grown-ups call the set of things you truly understand your circle of competence. Inside the circle, you can spot trouble early, ask sharp questions, and tell a real problem from a passing one. Outside it, you're flying blind - you can't tell "this needs one more tweak" from "this will never work," so you believe whatever the excited inventor tells you. Twain, outside his circle, had no way to judge the machine on its merits. So he judged it on feeling instead - the demo dazzled him, the dream thrilled him - and feeling is exactly what love feeds on.

See how the two mistakes hold hands. Because the machine was outside his circle, Twain couldn't judge it coldly; and because he couldn't judge it coldly, he fell in love with the dream; and because he was in love, he kept feeding it sunk cost after sunk cost. Staying inside your circle isn't just about picking better things at the start. It's also armour against the emotional trap later, because inside your circle you can actually tell when to stop. only put real money into things you genuinely understand - not because understanding guarantees you win, but because outside what you understand you can't even tell a small problem from a fatal one, so you end up trusting feelings instead of facts.

The humble move - the move that would have saved Twain - is to say, "This machine may well be brilliant, but judging machines is not my skill. It's outside my circle, so I'll pass, or risk only a tiny amount I can happily lose." A person who knows the edges of their own knowledge is far harder to ruin than a person who knows a lot but thinks they know everything.

The slip is almost never "I want to lose money on something I love." It's a chain of gentle, sensible-sounding thoughts, each one true-feeling, that together march you into the pit.

It usually sounds like this. "It just needs a little more time." Then: "I've already put in so much, I can't stop now." Then: "I remember how great it was - this is only a rough patch." Then, defensively, "Everyone who doubts it just doesn't get it like I do." Every one of those sentences is love talking, not analysis. And the tell - the thing that gives it away every time - is that none of them are about the future of the thing. They're all about you: your money already spent, your memories, your pride, your dream.

Now the honest cautions, because even a good rule can be swung too hard.

First, "don't get attached" does not mean "sell everything the moment it dips." Prices wobble all the time for silly reasons, and a good business can have a bad month or even a bad year while still being exactly the kind of thing you'd happily buy fresh today. If you answer the fresh-eyes question honestly and it's still yes - you'd buy it again, knowing everything you now know - then holding through the wobble is wisdom, not attachment. The cure for loving a stock is not restlessly dumping it; it's the calm, honest re-check. Someone who sells every holding at the first flicker of fear has caught a different disease - jumpiness - which quietly bleeds money through costs and bad timing. The point is to judge by the future, and sometimes the honest judgement is "keep."

Second, "stay in your circle of competence" does not mean "never learn anything new." Your circle can grow - that's wonderful. The mistake Twain made wasn't caring about a machine; it was betting most of his fortune on something he had not yet taken the years to truly understand. The healthy path is to widen your circle patiently and honestly, and to risk real money only inside the part you've genuinely mastered. Learning is how the circle grows; pretending is how you fall off its edge.

Third, letting go is not the same as never trying. Twain's deeper error wasn't that his machine failed - many good ideas fail, and trying brave things is fine. The error was refusing to see clearly once the facts had changed, and refusing to cap how much of his life he'd risk on one loved thing. You're allowed to back a dream. You're not allowed to let a dream, or your love for it, decide how much of everything you own it gets to swallow. The lesson isn't "never fall in love." It's "never let the thing you love touch money it could ruin you by taking."
