To know oneself, one should assert oneself.
Who seeks shall find.
Either you run the day or the day runs you.
To be a good loser is to learn how to win.
It's always too early to quit.
Go for it now. The future is promised to no one.
By failing to prepare, you are preparing to fail.
I can, therefore I am.
After a storm comes a calm.
Be gentle to all and stern with yourself.
If we would have new knowledge, we must get a whole world of new questions.
