I did not read the above reponses to your questions, so if this is a repeat sorry.
My first piece of advice is do what you love to do. If that is one of the two options then do it, if not, go to school and get the education you need to do what you love.
My second piece of advice is never work for family or friends. The hardest thing to do is keep a personal relationship away from a working relationship when you are working for friends and family. Do not work for either. Go out on your own and earn the job you want to do, do not settle for something because someone hands it to you. It's your life and your decisions and the future is based only on you. Go after whatever it is you want 110% and never give in or give up untill you are dead. You make the best out of these choices and you only.
