"When I was a boy of fourteen, my father was so ignorant I could hardly stand to have the old man around. But when I got to be twenty-one, I was astonished at how much he had learned in seven years."

I thought this is a Mark Twain quote but apparently it's not? It's still good regardless of who said it.
