I don't know what to think

I am sitting here in the Library at USU on the fourth floor trying to finish my Biology. I don't like biology, I don't understand it, but yet, I am in the class and I have to force myself to learn. I came up to Utah State University with the intent of becoming a Horticulturist, that plan was thrown out after the first week....and now, I don't know what I want to really do with my life. Lately though, I have been pondering about becoming a writer, because writing is something that comes easy for me, it is something that I love to do. The one problem is though....how do I know if I am a good writer? Everyone who reads my stuff just says the classic response: "It's good, I like it." You like it? Why do you like it? It never helps me. Maybe I can use this blog to post some writings and see what people think. Even if I were to become a writer, how the heck would I make money? Being a writer isn't really the best field to go into if you need to survive. I just hope with time, I will figure what I truly want in life and where I really want to go. Well, back to biology.
