I would first work on getting comfortable with myself and my personality and knowing what it is I want. If you feel you do not do well with supervision and want to work alone, etc. then I would take that into account and find a career that gives you most of that. If I got a lot of feedback that "everyone" thought I was too orderly and uptight, I would look harder at that to see if I wanted to work on any of my habits/thought patterns to see if I could fit better with others.
