If you think you can do it, you can.

I can, therefore I am.

The secret of getting ahead is getting started.

To know oneself, one should assert oneself.

Things do not happen. Things are made to happen.

What you do today can improve all your tomorrows.

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

Begin to be now what you will be hereafter.

Well done is better than well said.
