I can, therefore I am.

Be gentle to all and stern with yourself.

Do not weep do not wax indignant. Understand.

Well done is better than well said.

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

What you do today can improve all your tomorrows.

Either you run the day or the day runs you.

If you're going through hell, keep going.

To know oneself, one should assert oneself.
