Be gentle to all and stern with yourself.

What you do today can improve all your tomorrows.

Never complain and never explain.

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

The most effective way to do it, is to do it.

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

The secret of getting ahead is getting started.

I can, therefore I am.

By failing to prepare, you are preparing to fail.
