Never complain and never explain.

To know oneself, one should assert oneself.

By failing to prepare, you are preparing to fail.

If you think you can do it, you can.

The secret of getting ahead is getting started.

It's always too early to quit.

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.
