What should I choose for a career? (10 PTS)?

-At first I wanted to be a doctor but my grandmother said there would be long hours plus the time in college.. I don't think I could handle the preasure, I thought about thew next step down was a vetranarian.. I love animals but I don't know anything about that, I also thought about being a specalist. I also thought I could be a pro swimmer because I love to swim and I plan on joining the swim team when I can! I just don't know what to do with my life.. for each job I menchanded, what degree would I need to get those certain jobs (Either a doctor, Vet, Pro swimmer, specialist, Cheif) I also like to cook things lol.. but what degree would I need for those? How much could I make a year for each job? what would be the work hours? I want my career world planned out before I get out of high school (im in middle school... PLEASE.. no comments saying "your in middle school bla bla bla..you have so much time to plan this out bla bla bla..." I don't need that.. please..answer for each one.. DOCTOR, VET, CHEIF, SPECIALIST... what degree would I need for each one, what would be the work hours (full time and part time) and what would be the Average amount I would get pain in a year for all.. THANKS.. again (10 PTS)save yourself all that hassle and be a zookeeper, or a masseuse( salary AND tips)You're in middle school, you have so much time to plan this out.
