Education is like friendship: it brings help, comfort, strength, privilege and success. Friendship is unquentionably profitable. However, you must never value friendship for the profit that it brings. To treat friendship as a means is to lose the capacity for friendship. Your companion is no longer your friend when you begin to weigh him in the balance of advantage. So it is with education: the profit of education persists only so long as you don't pursue it.
