You don’t get confidence first and then choose. Choosing is how you get it.

Confidence is a result and people keep treating it as a prerequisite. Waiting to feel ready means waiting for evidence, and evidence only comes from having done something similar, which you cannot have until you start. Action comes first and the feeling follows, in that order almost every time.

Pick the smallest version of the thing you are avoiding and do it this week while still nervous. Apply, ask, go, speak, send. Afterwards, notice that the nervousness did not have to be resolved before you moved.
