I spent my first three years at the University of Florida not in a fraternity, spending most of my time doing homework. My classmates in engineering were incredibly boring people. My fourth year, I decided I couldn't do another year of it and I either needed to take some time off or make a radical change.
I joined a lower-mid fraternity(DTD - could have done "better" had I understood rush, but it was an excellent fit for me) and started enjoying college for the first time. I met my fiancee at a social there. My best memories of college are probably the time I "wasted" shooting the shit during lunch at my fraternity.
