Ability matters, of course it does. You can’t expect to play at the NBA level without some serious skill. But skill aside, people talk themselves out of giving their best effort long before that skill becomes the limiting factor. Or in some cases,  talk themselves out of even starting.  You are capable of more than you know. But often times we are the thing that holds us back from reaching our full potential. Our lack of confidence, is the thing preventing us from success.
