Be gentle to all and stern with yourself.

Do not weep do not wax indignant. Understand.

If you've got a talent, protect it.

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

By failing to prepare, you are preparing to fail.

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

It's always too early to quit.

If you think you can do it, you can.

To know oneself, one should assert oneself.
