If you aren't sure what you want to do with your life, there is nothing wrong with leaving college for a while to clear your head. In the 60's my father quit
college one day in the middle of a
quarter. He just decided that he'd had enough, packed up his shit, and left. Didn't tell his
professors. Didn't tell the
university, either. He worked for a year as a
freelance draftsman before deciding that he'd had enough of that, too, and having
gotten his mind right, went back to college and picked up where he left off. He finished and is now very successful in his line of work.
