Know or listen to those who know.

The secret of getting ahead is getting started.

The most effective way to do it, is to do it.

Do not weep do not wax indignant. Understand.

Who seeks shall find.

Never complain and never explain.

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

If you're going through hell, keep going.

To know oneself, one should assert oneself.
