To know oneself, one should assert oneself.
What you do today can improve all your tomorrows.
Expect problems and eat them for breakfast.
Do not weep do not wax indignant. Understand.
Wherever you are - be all there.
Know or listen to those who know.
By failing to prepare, you are preparing to fail.
Be thine own palace, or the world's thy jail.
Be gentle to all and stern with yourself.
Be kind whenever possible. It is always possible.
