Go for it now. The future is promised to no one.
To be a good loser is to learn how to win.
What you do today can improve all your tomorrows.
Expect problems and eat them for breakfast.
It's always too early to quit.
After a storm comes a calm.
If you've got a talent, protect it.
Problems are not stop signs, they are guidelines.
The dog that trots about finds a bone.
Who seeks shall find.
The odds are always against you no matter what your previous history is. You have to overcome the tendency to relax.
