Warren Buffett on not getting in your own way...

From July 1998 (via Tap Dancing to Work):

"So why do smart people do things that interfere with getting the output they’re entitled to? It gets into the habits and character and temperament, and behaving in a rational manner. Not getting in your own way. As I said, everybody here has the ability absolutely to do anything I do and much beyond. Some of you will, and some of you won’t. For the ones who won’t, it will be because you get in your own way, not because the world doesn’t allow you."
