It's always too early to quit.
Things do not happen. Things are made to happen.
You never know what motivates you.
If you've got a talent, protect it.
To be a good loser is to learn how to win.
If you think you can do it, you can.
The dog that trots about finds a bone.
Problems are not stop signs, they are guidelines.
Be gentle to all and stern with yourself.
Well done is better than well said.
I'm not hip, I'm not cool, I'm not glib.
