Is it enjoyable? I leave for college next year, but I don't know what I want to study. I have a great interest in math and mechanics, and I'd like to do engineering. I've narrowed down my list to Mechanical Engineering, Aerospace Engineering and Nuclear Engineering (I don't know, I guess I find Nuclear Physics interesting). I'd appreciate it if anyone who's doing/has done Aerospace Engineering (or any of the other two) can give me some input. Like pros and cons, what you get to do, if they regret it or not. That kind of stuff. Or perhaps someone would like to recommend something instead of these? Thanks.
