Personally I've just finished school, so I'm now going in to optional education (college, then university).
I wouldn't consider not going to either of the two above places. I mean, not only would you miss out on a LOT of education (and qualifications), you're also making friends and creating a backup plan for your life incase your job (whether it's online or not) fails.
MMO for me is just a hobby.. something to do on those boring evenings. I wouldn't want to be sitting infront of a computer screen all day... it'd get so dry!
