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

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

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

Either you run the day or the day runs you.

I can, therefore I am.

Do not weep do not wax indignant. Understand.

It's always too early to quit.

Always desire to learn something useful.

To know oneself, one should assert oneself.
