Cary Tennis, genius, speaking the invisibly obvious:

“If you create this condition that you must believe in yourself to go forward, you might not go forward. You must find a way to go forward without that condition. You do not need to believe in yourself. You just need to find a way to move forward and embrace the activity you are engaged in. You think that believing in yourself will give you the strength to go forward? It may not work that way. It may be that you go forward simply by going forward.”
