Never complain and never explain.

What you do today can improve all your tomorrows.

Be kind whenever possible. It is always possible.

You never know what motivates you.

Be gentle to all and stern with yourself.

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

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

By failing to prepare, you are preparing to fail.
