To know oneself, one should assert oneself.
If you've got a talent, protect it.
By failing to prepare, you are preparing to fail.
What you do today can improve all your tomorrows.
To be a good loser is to learn how to win.
The dog that trots about finds a bone.
Go for it now. The future is promised to no one.
Always desire to learn something useful.
If you think you can do it, you can.
It's always too early to quit.
It's a sad and stupid thing to have to proclaim yourself a revolutionary just to be a decent man.
