To know oneself, one should assert oneself.

Know or listen to those who know.

Problems are not stop signs, they are guidelines.

Never complain and never explain.

Who seeks shall find.

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

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

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

What you do today can improve all your tomorrows.
