Dropped out, no regrets. I think I decided I didn't want to to go college my first day of 1st grade. I absolutely hated, loathed, abhorred (I don't think there's a word strong enough) school my whole life and never wanted to make myself go through anymore than what was absolutely necessary by law if I had a choice in it. As a requirement for graduation, I had to take about 50% of my senior year classes at a community college (which I hated even more than regular high school), and somewhere in that year I let my friends, parents, school advisers, etc. talk me into going to a 4-year university the next fall. I tolerated it for a few months and decided I'd had enough. It's just not for me. At least I can say I tried it, but now I know it just isn't for me (too bad I had to waste a couple months of my life and a few thousand dollars to find that out, but what can you do).
That being said, although I don't regret dropping out for my own peace of mind, I do admit it kind of sucks to live in a world that's so unfriendly to people who are unwilling to go into thousands of dollars of debt for the better part of their adult life to get a piece of paper that says you can do/you know a lot about X so you can get a higher paying job than I can. But meh. That was my choice and I have to make the best of it.
I don't think I would be so anti-college (for me, I don't care what others do) if the school system in America actually made sense (to me). If it was more like other countries where you basically go and concentrate on only your major and things that are relevant to it, then I'd probably be all for it. But if I want to study biology and sciences, then sorry, I just don't have time (or the desire to dump extra money) for English or poetry or dramatic arts, you know?
