Bet on Yourself
This is the advice I received from a mentor. There is never a “good time” to — you just have dive in headfirst.
There won’t be anyone else in the world who will be a bigger cheerleader than yourself. Trust your gut, take that leap, and say “I’m betting on myself.” We can’t control anyone else and anything else in the whole wide world, so why not take that bet and go “I can do it”. Self-confidence is a muscle that needs to be exercised and practiced.
