Courage often begins before confidence has enough evidence to exist.

Courage does not wait for confidence, because confidence is built from evidence and the evidence only exists after you have acted. That means the first move is always made without the reassurance you were hoping to have, which feels like recklessness and is actually just the order these things occur in.

Stop waiting to feel ready and look for the smallest version of the action that would still count. Do that one, badly if necessary. It produces the first piece of evidence, which makes the next one slightly easier. Confidence assembles behind you, not in front.
