Hi. I'm at a very critical point in my life / education. In 3 months I have to apply to the university I will attend next summer. I'm torn between studying physics or biology - I have had biology for 6 months, physics only for 1 week in my whole life. But I've been interested in astronomy since I was 12, and was also an avid stargazer back then - then things happened in my life and I didn't touch my telescope for another 6-7 years (I'm 20 now). I have been interested in biology too since I was 12-13 and first read about Darwin, but ultimately, if I could do the math (which I'm not good at), astronomy would probably have my greatest interest. I have also considered geology - but it's not nearly as interesting as the other fields. But everytime I'm set on studying astronomy, I feel like I'm "betraying" myself, and that my reall "call" in life is astronomy - and vice versa. But astronomy was the first science to send chills down my spine, I admit (here thinking of my first telescope encounter with M31 on a clear winter night). One of the main reasons I'm considering biology is because I could, I assume, be outdoors a lot. I hate sitting still inside, especially when the sun is shining. A 8-16 office job doing say, accounting, would be torture for me. I HAVE to do science, and it's got to be meaningful. Do astrophycisists sit still all day, or do the also travel sometimes? But I'm really unsure as to how the daily life of an astrophycisist on job is. What does he do? Does he sit in front of a pc all day, calculating all sorts of abstract measures? I know they don't use telescopes that much. But what do they actually do? Research? Can somebody describe to me how a usualy day could look like? I really hope some people will answer - I'm literally blown away by all the possibilities of the different studies, and I find it VERY hard to choose one. So any guidance is warmly appreciated!! Thanks in advance. PS: Sometimes I get discouraged and almost want to drop science alltogether, because due to certain life circumstances I will be 21 when finish high school and start university - which is much older than the average student, especially the science students I think. Einstein said that if you haven't made your major contribution to science before you were 25, you would never amount to anything. And I haven't even graduated when I'm 25!
