You miss 100% of the shots you never take.
Forget past mistakes. Forget failures. Forget everything except what you're going to do now and do it.
When you do the wrong thing, knowing it is wrong, you do so because you haven't developed the habit of effectively controlling or neutralizing strong inner urges that tempt you, or because you have established the wrong habits and don't know how to eliminate them effectively.
-- W. Clement Stone
A journey of a thousand miles begins with one step.
