Also, don't listen to anyone else (especially me).
I have friends, co-workers and family who love sitting behind a desk. They can focus on the tasks and job assigned to them, and they feel satisfied when they leave work to come home and do the same thing again tomorrow. To some, work IS life, and its despite time just sailing on by, they are content to look forward to vacation, the weekends, or retirement.
Additionally, there are a lot of people out there who will tell you to stay in a job you hate because they frankly love their job. They get flexibility, "enough" vacation, enough pay, enough variety, that they kinda assume everyone else does too.
I've met ex-Surveyors who hated being out in the weather, and guys who retired never learning to use CAD or MicroStation, content to be outdoors everyday.
I've noticed in the last couple of years, mostly since working in a cube, that work can be busy, and I don't get stressed. They can ask me to work 50 hours a week driving for projects up north, and thats fine by me. Special projects outside the scope of my duties? Sweet. Sweeping floors? Great.
What stresses me out? The days when I'm not doing anything different.
I appear as a go-getter, as self-motivated, willing to learn, always ready to take on new responsibilities. My supervisors love this, but I don't do it so I can move up or get paid more, I do it because I HATE sitting in the cube.
I envy the maintenance guys, and I may move that direction.
Consider your options within the company. Maybe there is a job that requires more travel that others don't want. Maybe you can job shadow someone in maintenance or sales. You don't need more education to get out of a cube, you just need to appear willing to do work that others don't want to do.
