I picked my major my junior year of high school and never changed it. Not much help for you. However, my sister-in-law started at one school towards one degree, then changed schools the next year, then a third school the third year. She is really hurting IMHO because she will have gone for 7 or 8 years for a dual degree, like 160 credits. I had 181 (180 required for my BS) in 5 years. I hope it works out for her, but I look at it as 2-3 years longer you could be making $50k/yr vs. getting and extra $10k/year in school loans.

IMHO, you will find out with more experience in the business/working world that there are at least 10 ways in which one person is interested in earning a living. Just pick one that will pay to support your desired lifestyle and stick to it. The sooner will your reward be, which is earning the real money and enjoying the non-work part of your life.
