Never complain and never explain.

Know or listen to those who know.

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

If you can dream it, you can do it.

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

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

By failing to prepare, you are preparing to fail.

Be kind whenever possible. It is always possible.

Be gentle to all and stern with yourself.
