People don’t trust you because you did one good thing. They trust you because you never stopped doing it.

LEADERSHIP
One good act is a sample size of one, and people are right to wait; what convinces them is the twentieth time, when it is clear you behave this way regardless of the week you are having. Trust is inferred from a pattern rather than awarded for a performance. Consistency is the whole product.
Pick something small you can actually sustain, rather than something impressive you will abandon: replying the same day, turning up at the stated time, doing the washing-up without discussion. Keep it going for a month without mentioning it. The month is the point, not the act.
What good thing have you done long enough to be believed?
Free, with nothing to buy inside it.
