To know oneself, one should assert oneself.
Be kind whenever possible. It is always possible.
By failing to prepare, you are preparing to fail.
Know or listen to those who know.
Never complain and never explain.
Wherever you are - be all there.
If you think you can do it, you can.
Quality is not an act, it is a habit.
Be thine own palace, or the world's thy jail.
Be gentle to all and stern with yourself.
The most excellent and divine counsel, the best and most profitable advertisement of all others, but the least practiced, is to study and learn how to know ourselves. This is the foundation of wisdom and the highway to whatever is good.
