I had the same sort of problem, and now have a job that is a step in the right direction even though I don't see myself doing this in ten years. Not full-time, anyway. I might keep it parttime because my body loves doing it. My head needs a challenge too, though, so I am taking small steps towards that goal.
It really doesn't matter what you do. if it is a step in the wrong direction, you will be wiser, and it will be easier to find what the right direction is for you. Think about it as a process of calibration, like steve's recent blog post. You don't know what you want, so get any job and see what happens. Go pick berries for a season, become a day-labourer for half a year, work at mcDo, it really does not matter, because you will learn.
You are not going to learn a whole lot sitting in front of your computer, though. That will teach you facts and figures, but very little about
you.
To learn about you you need to interact with others, and then reflect.
Good luck, and be happy you are in this dillemma in your early twenties, and not in your late thirties like me
