I was considering posting in your thread, but I didn't feel like my reply would really be worth posting.
I felt the same kind of pressure I guess when I was in school, but it was far less from my family than my peers.
I chose the more 'stable' route of military, but that had a lot to do with lack of money for college. I'm not complaining, as I've grown tremendously from it. But I think if you feel that it is important to follow your dreams, you should.
