To know oneself, one should assert oneself.

It's always too early to quit.

What you do today can improve all your tomorrows.

Who seeks shall find.

Go for it now. The future is promised to no one.

To be a good loser is to learn how to win.

By failing to prepare, you are preparing to fail.

Either you run the day or the day runs you.

I can, therefore I am.
