It's always too early to quit.
The secret of getting ahead is getting started.
The most effective way to do it, is to do it.
The dog that trots about finds a bone.
If you're going through hell, keep going.
You never know what motivates you.
Always desire to learn something useful.
To be a good loser is to learn how to win.
Either you run the day or the day runs you.
Expect problems and eat them for breakfast.
Don't play too much golf. Two rounds a day are plenty.
