Only the educated are free.
It's always too early to quit.
Quality is not an act, it is a habit.
I can, therefore I am.
Know or listen to those who know.
Always desire to learn something useful.
Be gentle to all and stern with yourself.
Be thine own palace, or the world's thy jail.
Be kind whenever possible. It is always possible.
Either you run the day or the day runs you.
He who devotes sixteen hours a day to hard study may become at sixty as wise as he thought himself at twenty.
