You don’t need to be fearless before you start. Fear shrinks after you start, rarely before.

Waiting to feel ready assumes the fear leaves first and the action follows, when the order is nearly always the reverse. Before you begin, your head has only the imagined version to work with, and imagination is worse than reality at almost everything. The actual thing supplies details, and details can be handled in a way that dread cannot. Starting is how you collect the evidence.

Take the first real step on whatever you have been circling, today if possible, before you decide how you feel about it. Five minutes of contact beats an hour of preparing.
