Know your exit before you enter. That’s not doubt, it’s being an adult about it.

Knowing how you would leave is not a shortage of belief. It is the difference between a decision and a trap, because you walk into the party, the job, the trip or the agreement already aware of what getting out would cost and how it would work. That knowledge usually lets you relax inside the thing rather than commit less.

Before the next thing you say yes to, answer two questions. How long am I in for, and what does leaving look like. Those answers take a surprising amount of pressure off the decision itself.
