To know oneself, one should assert oneself.

Be gentle to all and stern with yourself.

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

Who seeks shall find.

Quality is not an act, it is a habit.

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

Leap, and the net will appear.

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

Know or listen to those who know.
