Know or listen to those who know.

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

Well done is better than well said.

If you're going through hell, keep going.

Do not weep do not wax indignant. Understand.

By failing to prepare, you are preparing to fail.

It's always too early to quit.

What you do today can improve all your tomorrows.

Never complain and never explain.
