I have a Ph.D. in cell biology. And that's really manual labor. I mean, experimental science, you do it with your hands. So it's very different. You're out there in a lab, cleaning test tubes, and it just wasn't that fascinating.
A man has to learn that he cannot command things, but that he can command himself; that he cannot coerce the wills of others, but that he can mold and master his own will: and things serve him who serves Truth; people seek guidance of him who is master of himself.
