Know or listen to those who know.

Without hard work, nothing grows but weeds.

The secret of getting ahead is getting started.

Be gentle to all and stern with yourself.

The dog that trots about finds a bone.

If you're going through hell, keep going.

Quality is not an act, it is a habit.

To know oneself, one should assert oneself.

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