Luck? I don't know anything about luck. I've never banked on it and I'm afraid of people who do. Luck to me is something else: Hard work - and realizing what is opportunity and what isn't.

In life, all good things come hard, but wisdom is the hardest to come by.

I think knowing what you cannot do is more important than knowing what you can.

The more things you do, the more you can do.

I'd rather regret the things I've done than regret the things I haven't done.
