I remember it being a little bit scary at first, for sure. Going away to college is a very big life change for most people. But, it was also a lot of fun, social, and a very challenging learning experience, both in class and in life!
I can still remember the first day, when my folks dropped me off at my dorm, helped me unload, and then drove away. I didn't know anyone on my floor, and I didn't know my way around. I was scared to tears!
But, I quickly discovered that everyone else was in the same boat. So, it didn't take long to make friends, and figure everything out.
As Luke already mentioned in his answer, there were stressful times, like during exams, and when multiple papers and projects are due at one time. I really had to work hard, manage my time wisely, and learn not to procrastinate. That was a tough lesson for me, since it seemed like there was constantly something fun going on that I didn't want to miss. There was always a roommate or friends or sorority sister who wanted me to go out, when I knew I needed to stay in and study. I'm glad I figured out how to buckle down when needed, though, because having my college degree helped me land a job in a career field I enjoy.
In addition to all my studies, I also had to learn how to take care of myself without help from my parents. College was my first time living on my own, and I had to get myself up on time, manage my own schedule, get myself to class, keep track of my class assignments and due dates, do my own laundry, manage my social life, etc.
College is a major life transition for anyone, but it can also be a wonderful, and exciting learning experience. It can even be a chance re-invent yourself, if you wish - start fresh to become the best possible version of yourself! Enjoy!
