Habits, health, money and time. How to actually keep up with your whole life.
A savings goal you will hit has four things a vague one does not: a specific number, a deadline, the weekly amount worked out from those two, and an automatic transfer so you never rely on willpower. Then you make the progress visible.
An implementation intention is an if-then plan: when X happens, I will do Y. Research shows these dramatically outperform vague goals. The trick is a specific cue and a specific action.
People are measurably more likely to start on a goal right after a temporal landmark, a Monday, a first of the month, a birthday. It is called the fresh-start effect, and you can plan around it.
