*There's only one corner of the universe you can be certain of improving, and that's your own self.
*People never improve unless they look to some standard or example higher or better than themselves.
*He who stops being better stops being good.
*Self-education is, I firmly believe, the only kind of education there is.
You can't have a better tomorrow if you are thinking about yesterday all the time.
*What you get by achieving your goals is not as important as what you become by achieving your goals.
