Which do you think is more difficult/exhausting? Do you think that physical labor is looked down upon?
For me, the mental stuff is a lot more draining. Having worked on my MS degree and as a research assistant for the past two years has been hell. Especially the last couple months where I have been putting in 12+ hour days everyday in front of the computer just to be done by the end of summer. Though, I figured I'd see it through since I made the financial investment and a degree would be something to fall back on.
I think that I've developed such a disdain for sitting on my ass all day everyday that I may starting working a physical labor job once I'm done with school. Never thought I'd hear myself say this but the oil fields are looking pretty good right about now.
