Exactly lol. What's wrong is humans is that they don't give importance to what's ACTUALLY important
My health is fucked, maybe for life, because I made a stupid choice in the face of pressure, a choice which meant unhealthy overdoses of stress and an unhealthy lifestyle of sitting on my ass all day and cramming. So now my digestive system is chronically messed up and I can't do most of the things I thought I'd do after suffering a stressful couple of years through, like going out. For anything. THAT'S what it took for me to realize what was important.
No, actually, I knew what was important even then. But I took the path of least resistance. I KNEW what I was doing was bad for me, but I did it because others would give me hell if I didn't. I was weak, and I chose wrong- KNOWING it was wrong- so now I'm being punished for it.
Sorry for the textwall
Anyway.
That's wonderful! I remember you were having a hard time at your old job, we talked about it both here and in Life Issues. The decision was a long time coming and I'm glad you made the decision and that it's giving you happiness
I know it's not that easy, but does he have to go back to the same job?
After school I chose what would make me happy, too. My body prevents me from really being happy, but I'm in a MUCH better place now. It's still bittersweet because it's a student hostel- so I can't control what I get to eat, and I have to deal with horrible public bathrooms- and I not only don't get to go out and do much, but I'm late for classes and miss events that happen right on campus (thanks, body.) That hurts, because I'm not going to get such opportunities dropped on my lap anytime except in college. But I guess I have to be content with how much I'm able to do.
It's definitely not easy- it took me
months to get my mother around to the idea that I wasn't going to study in med school but in a liberal arts college- and I still get shit from a lot of people about it, but I'm able to disregard those opinions as not worthy of brain space
Seriously, stress is just not worth it. It can have pretty drastic consequences and long-term stress will just screw you over.

I hope your partner is able to figure something out as well.
