Why Is Change So Hard?

A locksmith of forty years says the sentence customers use most often is this lock is broken, and that it is wrong about nine times in ten. The lock is generally in excellent condition and doing precisely what it was built to do, which is to resist. What has changed is the key, or the frame, or the season, or the expectations of the person on the doorstep. He thinks this is also the correct description of why people cannot change their lives, and he is not being poetic about it.

Every habit you cannot break, he points out, is currently succeeding at something. The late-night scrolling is delivering a reliable, cheap end to the day. The overwork is producing a defence against a question you would otherwise have to answer. The temper is clearing a room. Nothing survives in a life for years without paying rent, and attempts to remove a behaviour while leaving its function unmet fail on a predictable timetable — usually eleven days, in his own experience of quitting cigarettes four times.

This reframes the work. Instead of asking how do I stop, he asks what is this doing for me, and what else could do it. The answer is often smaller and more embarrassing than expected: the cigarette was a reason to leave the building and stand outside without a task. The replacement was not willpower; it was going outside without a task. He says almost every durable change he has seen, in himself and in a long line of customers who tell locksmiths remarkable things, has this structure — not a removal, a substitution.

The second reason change is hard is that identity moves slower than behaviour and eventually pulls it back. Someone who has been the unreliable one for twenty years can be reliable for a fortnight, but the fortnight is experienced as acting, and acting is tiring. He thinks this is why so much progress collapses at precisely the moment it starts working: success creates a mismatch between what you are doing and who you believe you are, and the cheapest way to resolve a mismatch is to stop doing the thing.

His practical advice is unromantic. Change one thing, keep everything else identical, and make the change small enough that you do not need to feel motivated to do it, because motivation is a fair-weather asset. Tell almost nobody, since announcing an intention delivers a portion of the social reward in advance and quietly reduces the pressure to earn the rest. And expect the first three weeks to feel worse than the old arrangement, because they will; you have removed a working solution and installed a prototype.

The last thing he says is offered as a comfort and lands, at first, as the opposite. If the change were easy it would already have happened. The difficulty is not a sign that you are weak or that the goal is wrong. It is a measurement of how well the current arrangement has been doing its job, which means the resistance you are feeling is, strictly speaking, evidence of your own past competence at solving a problem you have now outgrown. The lock is not broken. You are simply, finally, standing at the door with a different key.
