To know oneself, one should assert oneself.

Things do not happen. Things are made to happen.

It's always too early to quit.

Do not weep do not wax indignant. Understand.

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

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

By failing to prepare, you are preparing to fail.

I can, therefore I am.

Be gentle to all and stern with yourself.
