To know oneself, one should assert oneself.

Be gentle to all and stern with yourself.

By failing to prepare, you are preparing to fail.

Begin to be now what you will be hereafter.

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

I can, therefore I am.

Leap, and the net will appear.

What you do today can improve all your tomorrows.

If you think you can do it, you can.
