I figured out (after dropping out ;) that college isn't about the diploma but about the connections you make. Add to that that you'll learn a shared vocabulary and 'way of thinking' which will allow you to communicate better with those connections. So if you want to know what to study, just ask yourself which company of graduates you would like to belong to. It'll also help with that sense of identity you felt you were missing.
