The most effective way to do it, is to do it.

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

Know or listen to those who know.

If you think you can do it, you can.

Be thine own palace, or the world's thy jail.

Well done is better than well said.

Be gentle to all and stern with yourself.

Leap, and the net will appear.

I can, therefore I am.
