I can, therefore I am.

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

If you think you can do it, you can.

Either you run the day or the day runs you.

Things do not happen. Things are made to happen.

Be gentle to all and stern with yourself.

The wise does at once what the fool does at last.

It's always too early to quit.

What you do today can improve all your tomorrows.
