If you've got a talent, protect it.
Only the educated are free.
Without hard work, nothing grows but weeds.
Know or listen to those who know.

Be thine own palace, or the world's thy jail.
Always desire to learn something useful.
Be gentle to all and stern with yourself.
Well done is better than well said.
