Stop waiting until you are ready. As soon as you are ready its already too late.
No one learns by being successful at everything they do. The biggest lessons are learned from the biggest failures. It takes no courage to keep swinging if you win. The real courage comes from keeping on going after you have taken a lose. The greatest teams in sports do not lose twice in a row. They rebound from the loss get better.
The real success is who you become and how you look at yourself.
