Perhaps the most important lessons you'll learn in college are the ones you learn outside the classroom. Figuring out how to live with someone involves respecting differences, sharing, being courteous, accepting others for who they are, and much more. You'll find that sharing space builds character.
While most freshmen do miss the privacy of their homes, they also find comfort in sharing company with others who are experiencing the same issues—difficult courses, living away from home, balancing school work and social life, and a whole lot more. In fact, while there are many alternatives for roommates who don't get along, most do stick it out, and solve their problems by talking it out.
Keeping lines of communication open is essential. Before you even step foot in your dorm, give your roommate a call and find out who you'll be living with for the next year. Discuss important issues and establish rules. come to an agreement about quiet hours. make a schedule so that you can both enjoy the room at different times. If you make house rules, and communicate openly and often, you can avoid unpleasant surprises down the road.
Be willing to compromise. You and your roommate may not agree on everything, but you both have to be willing to compromise a little bit. If you're a slob and she's a neat freak, you should start cleaning up, at least in the parts of the room you share. And she should try to be flexible and realize your unmade bed doesn't affect her.
