Yeah, I went a fairly big university, hated walking around in the heat. I majored in biochemistry. Fat lot of good that did. TBH I still don't know what I want to do with my life. I'd like to write a book though.
You should pick a major that you enjoy. But also consider if it will land you a decent paying job. Also that sucks, college can be such a rip off, can you return the book?.
