Never complain and never explain.

You never know what motivates you.

I can, therefore I am.

Leap, and the net will appear.

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

Do not weep do not wax indignant. Understand.

By failing to prepare, you are preparing to fail.

The wise does at once what the fool does at last.

To know oneself, one should assert oneself.
