Tired...

I am sooooo tired... ... Berkeley, compared to my JC, is totally a whole new pace of lifestyle, homework is due every week, with no solution handbook to copy from, math problems are much harder, professors talk much faster, and students are much smarter here. Man, I hope I could survive the next two years. Sometimes, sitting in the vast and hollow reading room of the library, slaving over my perverse math homework, I can feel so lost. It's as if the more I learned, the vacuous my head becomes, what's the point in finding the friggin' null space of some friggin' vector space? what have I got myself into?
