Know or listen to those who know.

The secret of getting ahead is getting started.

Never complain and never explain.

The dog that trots about finds a bone.

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

To know oneself, one should assert oneself.

It's always too early to quit.

Begin to be now what you will be hereafter.

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