I had friends in college ho got involved with fraternities; it just wasn't for me. I found campus activities that interested me and met TONS of people that way.
For example, desktop publishing was a novel concept in 1989, but I quickly mastered laying out an 8 1/2 x 11 to make it into a newsletter. I was soon freelancing for many offices on campus and got to know a lot of the residence hall staff. I worked in five or six of their offices around campus. I also designed newspaper ads for the student union--my first girlfriend on campus was an ad rep--not mine, but one who had noticed me come in evry week and who had asked her boss, my rep, about me. The girl was a senior and I was a freshman.
I got a job working at the front desk in a high-rise, so I met all or s co-workers from that side of campus during training. We'd split back into building or even community staff--that's 3 communities with 3 buildings each--but because I'd worked in all of the community management offices, I'd sometimes get a call to ill in at a building I'd ordinarily work in.
I worked conferences over the summers, exposing me to literally thousands of people of all types--you'll likely know what OM is--we hosted 6,000 on campus and 13,000 total attendees my last year there, if that gives you any idea of how big an operation it was.
I eventually managed the desks, both summer and during the year, and then got promoted to the highest position I could possibly have as an hourly student--Assistant to the Director of Summer Conference Housing. That meant I had to know hundreds who operated a total 6000 beds evey summer.
I got a radio show and pushed the station to do my show out of the studio occasionally. They insisted we didn't have the equipmrnt, but we did: all I needed was a POTS line and I could be on the air from anywhere. And I was, a few times, in front of thousands of people.
At one point, I sat as 1 of about 50 on a board that controlled a $1M rotating fund that brought big-name entertainment to campus.
I was invited to start a campus daily paper. I did all kinds of stuff. Get out and meet people.
