**DISCLAIMER: the following is only through the experiences the writer (I) have felt or have seen through fellow college friends.**
1) Laundry
Know how to do your laundry. Please, it helps the whole system if you do.
2) Declaring your major your first day
Do not say you are declaring your major if you still do not know what it is 100% or have not taken a single class in it. It is good to have a good idea but keep an open-mind! Who knows, maybe that econ major you thought you really wanted to go for turned into art education because you realized working with kids was your passion, or you never realized just how bad at math you really were.
3) Your finances
Finances are hard to manage, even adults well out of college struggle. If you have work study, don't wait until the 3rd week of school to get an on campus job because chances are they're already taken.
4) Relationships
Fact: relationships happen in college. Myth: every college relationship will last a lifetime.
5) Food
Food is going to suck after a while, so if there is a grocery around you or you have a friend with a car that you can temp with good cooking, then it is time to follow a recipe at least.
6) Friends
Especially for out of state students, being a freshman is just as hard in college as it was in high school. So many will clump into a small-tight knit group that will to be together for all of eternity. Except now you see these people every single day. You will have a couple of friends that you be as close with if not more after graduation; however, they may not be the ones that you met during orientation.
7)Roommate(s)
Roommates similarly fall under the friend category in that they are a fast way to make a friend but very unlikely to last a lifetime. There is no singular meme that can describe a roommate relationship, because each relationship is different.
You guys may be biffls and room with each other all four years, or be really close then have a huge falling out, which results into a war zone. Or not know that the other one exists. College humor has a pretty funny video about roommates HERE.
8) Health
Regardless if your healthcare or if the health center sucks, your health comes before anything else, bottom line.
9) Partying-Academics balance
Nobody gets the "balance" right the first time, that is why the words "mistake" and "Trial-runs" were invented. Make time for fun and make time for academics. Ultimately think about if you are spending X amount of dollars in your education and if how you are spending it is worth it.
And finally...
10) Sleep
You will pull a all-nighter, but if you actually plan ahead, then you will have one of those (very) few days when you can just sleep in because naps will never feel so good.
