Be thine own palace, or the world's thy jail.
Only the educated are free.
Without hard work, nothing grows but weeds.
Always desire to learn something useful.
Never complain and never explain.
Be gentle to all and stern with yourself.
It's always too early to quit.
You never know what motivates you.
Leap, and the net will appear.
The dog that trots about finds a bone.
A good teacher must be able to put himself in the place of those who find learning hard.
