Be gentle to all and stern with yourself.

I can, therefore I am.

Either you run the day or the day runs you.

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

To know oneself, one should assert oneself.

If you think you can do it, you can.

Know or listen to those who know.

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

Well done is better than well said.
