To know oneself, one should assert oneself.

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

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

It's always too early to quit.

What you do today can improve all your tomorrows.

If you think you can do it, you can.

Be gentle to all and stern with yourself.

The secret of getting ahead is getting started.

Well done is better than well said.
