I have a couple friends who were big outdoor types who became software engineers and then after making some money for a few years went and found more outdoorsy jobs (think forest service jobs).

The point is not that an outdoorsy job is great for you, but that you may want to consider what kind of things make you happy and see if you can find a job doing something like that. These folks loved being outdoors before become engineers and were happy to go back to being outdoors for work.
