Know or listen to those who know.

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

Never complain and never explain.

Be kind whenever possible. It is always possible.

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

Be gentle to all and stern with yourself.

Go for it now. The future is promised to no one.

If you think you can do it, you can.

What you do today can improve all your tomorrows.
