It's always too early to quit.
If you've got a talent, protect it.
Without hard work, nothing grows but weeds.
You never know what motivates you.

Things do not happen. Things are made to happen.
To know oneself, one should assert oneself.
To be a good loser is to learn how to win.
Expect problems and eat them for breakfast.
The dog that trots about finds a bone.
