It's always too early to quit.
If you can dream it, you can do it.
I can, therefore I am.
To be a good loser is to learn how to win.
If you've got a talent, protect it.
If you're going through hell, keep going.
Do not weep do not wax indignant. Understand.
Know or listen to those who know.
Never complain and never explain.
Expect problems and eat them for breakfast.
I've always regarded nature as the clothing of God.
It's hard for me to think of others because I'm not particularly in sympathy with the music of this century.
