"Page, I will not have you look upon yourself as hopeless in Arithmetic," she said to me one day when I despaired of ever understanding what seemed to me a very intricate problem. "Lewis Carroll was a great mathematician and still he wrote the delicious classic that you and I are so fond of. Now I think minds that appreciate the same things must be similar. I believe there is a corner of your brain that is absolutely unexplored and that corner corresponds to the great fertile area in Lewis Carroll's. All it needs in you is working, digging, cultivating to produce fruit."
