Know or listen to those who know.

To know oneself, one should assert oneself.

Expect problems and eat them for breakfast.

Be gentle to all and stern with yourself.

The secret of getting ahead is getting started.

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

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

I can, therefore I am.

Do not weep do not wax indignant. Understand.
