Know or listen to those who know.

Things do not happen. Things are made to happen.

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

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

Wherever you are - be all there.

Well done is better than well said.

What you do today can improve all your tomorrows.

Never complain and never explain.

To know oneself, one should assert oneself.
