The psychologist Peter Gollwitzer spent years studying why wanting something is not enough to make you do it. His finding fits in a formula: goals get done far more often when you turn them into an 'if… then' plan. Not 'I'm going to exercise', but 'if it's Monday, Wednesday or Friday, then at seven I put on my trainers and go out for twenty minutes'.
In a classic study on physical exercise, about a third of the group that merely stated their intention followed through; of the group that wrote down exactly when and where they would do it, more than ninety per cent.
Why does it work? Because it takes the job away from willpower and hands it to your environment. The cue — it's Monday morning, I've just had dinner, the alarm goes off — triggers the behaviour without passing through the inner debate, which is exactly where goals go to die.
It works in the negative too: 'if I feel like checking my phone while studying, then I leave it in the other room'. The golden rule: don't plan outcomes; plan triggers.
