To know oneself, one should assert oneself.

Things do not happen. Things are made to happen.

If you think you can do it, you can.

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

Do not weep do not wax indignant. Understand.

I can, therefore I am.

Leap, and the net will appear.

Without hard work, nothing grows but weeds.

Know or listen to those who know.
