I think I have replied to this thread back when I first joined TeenHelp, but everything hs changed so I am going to put a new answer here.
When I was little I wanted to be a veterinarian, but when I got into high school, I wanted to be musician or a chemist. When I got into college and declared my major as chemistry my freshman year, I really wanted to be a chemist. However, when I got to the spring semester of my sophomore year, I decided that chemistry was too difficult for me and changed my major to biology. Now when I graduate college, I am hoping to get a job where I am working with something that has something to do with the environment, conservation, and/or biotechnology.
