It's always too early to quit.
If you think you can do it, you can.
If you've got a talent, protect it.
To know oneself, one should assert oneself.
I can, therefore I am.
If you're going through hell, keep going.
To be a good loser is to learn how to win.
Go for it now. The future is promised to no one.
The dog that trots about finds a bone.
After a storm comes a calm.
I think America has more than enough maturity and intelligence to start exercising its world leadership responsibly.
