I wouldn’t overly focus on what you think you want to do before going into school. I majored in philosophy and math as an undergrad, then went to grad school to become a clinical psychologist. Unless you want to be a doctor (which has a pretty specific track you need to do) there’s plenty of room to change your mind. Remember you have to be there for 4 years so make sure you’re ok with the geographic area. Living in the dorms is how I made most of my friends in college, and you will miss a big part of the experience if you aren’t there. I wouldn’t suggest eschewing that unless you absolutely need to financially. Once you get to school, never cut class, always do the reading, and talk a lot during in-class discussions. As professors we all know if you did the reading or not because people who don’t read usually ask questions answered by the reading. Plus if we recognize you, we will inevitably be more willing to cut you a break when it comes time for grading. Don’t plagiarize because it’s super easy to catch these days. Otherwise remember to have some fun. College is much more than education to get a job.

Also if you’re heterosexual, as a social FYI, always have protected sex until you’re in a committed relationship of whatever variety you’re into—no one’s dick is too big for a condom so don’t buy that shit if someone tells you that.
