Practice is a substitute for talent; however, there is no substitute for practice.

Never do business with friends, family, or church folks, lest you live to regret it.

If you have no respect for a given person, there is no reason to worry about what they say about you.

A man of ordinary talent will always be ordinary, whether he travels or not; but a man of superior talent will go to pieces if he remains forever in the same place.

...You can do something extraordinary, and something that a lot of people can't do. And if you have the opportunity to work on your gifts, it seems like a crime not to. I mean, it's just weakness to quit because something becomes too hard...

A skill you don't use, you'll lose.
