I am not going to say anything about senioritis because I was ready to get out of there and I'm sure you are too; however, in your last months living at home you should take advantage of the luxuries you will not have in a college dorm. The part of college seen in movies is great, the rest of it is incredibly inconvenient. It is better to come to terms with this While you still have plenty of time to prepare and enjoy yourself.
Perhaps one of the most annoying examples is the shower. Enjoy your hot, barefoot showers now because soon enough you will have no water pressure and a drain clogged with other people's hair. Enjoy touching your feet to the floor in the shower and the bathroom because though it seems weird, it's a small thing taken away from you in college when you have to wear shoes everywhere.
Enjoy your last summer with your friends. After this summer, any free time you take is a sacrifice. For example, if you want to go home for the summer after your freshman year and be with your friends, you have to sacrifice an internship. If you sacrifice an internship, you risk falling behind on your resume, and so on. I'm not saying you can't do that, but it is not an easy choice anymore.
Get organized. If you're like me you probably got good grades in high school by relying on your own mind. You think I can remember what I have to do for tomorrow. In college, it is much more difficult to live by memory. There are classes that only meet once or twice a week and meeting and appointments in between that are impossible to mentally keep straight. If you do not yet have an organizational system that works for you, get one.
I do not mean to sound pessimistic about school. College is great and you will meet a lot of people and make a lot of memories that will stick with you for most of your life. I'm just saying be ready.
