You just go ahead ...

We worry about our adequacy. Am I skillful enough? Am I good enough to do what I am doing? It is so uncertain, and at some point, there’s no help for it. To find our way in life, we will have to have some strong conviction. We’ll just have to go ahead. If you wait until you’re good enough or you’re skilful enough or until you are sure of yourself and are certain to get it right, it may never happen. At some point there’s no help for it, and you just go ahead ...
... You start from where you are standing still, and you accelerate yourself into activity - into hearing and seeing and acting - where things are coming along. But at the same time, there’s no help for it. If you wait for I’m inspired or I’m sure it’s okay, then your whole life may be spent waiting. And over time you may find that worse than going ahead.
