How do you know you won't like going out? And most people don't go out every night... it's usually 1, maybe 2 nights a week. Plus what's wrong with joining societies and if not making a society to give you something to do? By doing all of the above you'll actually find people who do like the stuff you mention whereas if you just sit in your room all night and mope about on TSR you're never going to find people who like doing the stuff you want to do.
