This "crisis" hit me when I was 27 and I still struggle with it today (now 36). I crave manual labor type of work (frame houses, etc), but I couldn't support my family the way I want to on those salaries. I've thought about going into Surveying, but it would still be a massive pay cut.
It's not a cure-all, but I've thrown myself into my cycling and it's helped quit a bit. Winter is still brutal and I suffer from SAD, but we're actually moving at the end of the school year to warmer climates (looking at Dallas, Austin, and Phoenix).
But you aren't saddled with much. There's nothing wrong with transitioning to the "simple life" (except it would make me jealous). Learn to be a mechanic, etc.
I think the reason people like us get fed up with the rat race is because, as Peter said in Office Space, we weren't meant to live in cubes. We're meant to move around and be physically active. When we spend 8 hours a day chained to a desk, our bodies suffer physically and mentally. It's why we have such difficulty sleeping, getting up, staying positive.
Do something that requires you to move around more than 50% of the day. I guarantee you'll sleep better and be happier
I tell my kids: if you grow up and spend more than half your day at a desk, you've learned nothing from me
