I'm a political activist in search of a similar soul. ;-) I throw myself into whatever it is that I'm working on/fighting for and would love to meet a kindred spirit who wouldn't mind dropping everything and traveling to where we're needed in the country (or indeed the world).
I have a backpack and sleeping bag that I can live out of indefinitely and it would be awesome if you have a similar mentality; be it Chicago, D.C., New York, New Haven, Boston, Thailand, or Prague we're off to (just to list some places I've been to).
Now this kind of life obviously doesn't net one a lot of income, however, a person attracted to this lifestyle would feel (as I do) that there are plenty of things more important then financial "success" namely living a good and interesting life ad trying to change the world for the better. :-)))
