Be gentle to all and stern with yourself.
Be thine own palace, or the world's thy jail.
I can, therefore I am.
Never complain and never explain.
Without hard work, nothing grows but weeds.
To know oneself, one should assert oneself.
Quality is not an act, it is a habit.
Only the educated are free.
Know or listen to those who know.
By failing to prepare, you are preparing to fail.
