It is up to you to define your college experience. Do not depend on anyone else to do that for you. Whether you chose to become a part of Greek life, SLGs, or staying independent, that is strictly your decision.
Freshman year was definitely an interesting time when it came to making friends. I remember making so many new friends during O-Week and then suddenly seeing them disappear as time went on. This sort of thing happens throughout the year. You see your circle of friends constantly growing and shrinking. Come spring semester, a lot of your friends will be rushing fraternities, sororities, and SLGs- you may find yourself rushing too.
I ended up rushing a SLG my freshmen year and I do not regret it. I found the environment of a SLG more fitting for me than that of a fraternity. Everyone I met during the process was welcoming and enthusiastic to meet me. I do not regret my decision of joining the Round Table community. I made so many great memories and built strong relationships. I have found my family at Duke.
I believe that my experience with finding my place at Duke was due to the fact that I was not pressured to join a specific group or organization. Everything that I did was done at my own will. I tested the waters with several things: DSG, Crew, and other clubs. Freshman year is definitely the best to time explore your options because all of your peers are also scrambling around trying to find their niche. It gets a little more difficult as the years go by as people already have established themselves in a particular group, but it is not impossible to do.
If you are willing to put in the effort, then you will get a great college experience in return. Do not sweat the small stuff. Just be yourself and have fun.
