To know oneself, one should assert oneself.

Know or listen to those who know.

I can, therefore I am.

If you think you can do it, you can.

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

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

Problems are not stop signs, they are guidelines.

Never complain and never explain.

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