" Barely, but I did. Then in college I did really well. Can you imagine that? Which is why I went to graduate school. But that was probably a big mistake. I should have quit while I was ahead. You see, my problem is I don’t know whether I’m smart or if I’m stupid. I’ve done well, and I’ve done poorly, and I’ve been told that I’m gifted and I’ve been told that I’m slow. I don’t know what I am. "
