“It was clear that if I didn't spend the rest of my life concentrating on string theory, I would simply be missing my life's calling.”

The Autobiography of Malcolm X (1965)
Context: I told the Englishman that my alma mater was books, a good library. Every time I catch a plane, I have with me a book that I want to read—and that’s a lot of books these days. If I weren’t out here every day battling the white man, I could spend the rest of my life reading, just satisfying my curiosity—because you can hardly mention anything I’m not curious about.
