I'm in a bit of a crossroads in my life right now. I've been in junior college for a while now, with the intention of transferring to a university and eventually getting a masters in history. It's my intention to become a professor at the junior college level, but I have my doubts. I know what the job market in academia is like, though it isn't quite as bleak where I live. My grandfather is also offering me an opportunity to work for him and learn from him. He's incredibly skilled in a very esoteric trade, and he pays pretty well. My uncle and brother already work for him, and they seem to enjoy it. Thing is, it's a big commitment. 80-100 hour weeks at times, sometimes out working in extreme heat, and it would keep me away from home and away from my girlfriend. All of that I can live with, but I know it would nag at me, the thought that I could've done what I'm really passionate about (i.e. teach history), which it must be said is probably an easier life than trade work.

What on earth should I do? I'm at the point in my life that I should be making some real money, though I'm not hurting for it right this moment. If I can't get the degrees without a mountain of debt, I likely just won't do it, but even if I can manage that, I'd like to know that it won't be impossible to find a job that doesn't involve treading water as an adjunct.

Edit: Wow, I did not expect this many responses. Thank you all so much for your kind words and insight. If nothing else, you've all reassured me that I'll probably be alright either way. I've at least got a fair few options to choose from, and I know many would gladly trade places with me. I'll do my best not to waste it.
