Why small steps win

Most resolutions do not fail for lack of willpower but because of the wrong dosage. Someone who decides on 1 January to train five times a week has not taken on something their everyday life can carry. They have taken on an exception and called it a rule.

The arithmetic everyone knows and nobody applies

One per cent of improvement per day compounds to thirty-seven times over a year. The number is famous, it is in every self-help book – and it is still misleading, because nobody improves by one per cent every day for a year.

The other direction is the interesting one: one per cent of decline per day leaves almost nothing at the end of the year. Both curves are unspectacular as long as you look at a single day. That is exactly why small steps feel like nothing – and exactly why they work.

Finding the right size

A habit is the right size when you would have managed it even on your worst day of the past four weeks. Not on an average day – on the worst one. Anything above that is a resolution that breaks on the first difficult day.

In practice that usually means: halve it. And if it still hurts, halve it again. Ten minutes of reading instead of an hour. One sentence in the journal instead of a page. The trip to the gym, without a training plan.

Let it grow, do not plan it

The second mistake comes later: as soon as it runs easily, the target goes up – ten minutes become thirty, and two weeks after that the whole thing is over. Instead, keep the habit small until it is boring. Boredom is the sign that it has settled.

Only then may it grow, in the same dosage as at the beginning: inconspicuously small.
