1. Not spending more time with my grandfather.
My grandfather was a very intelligent person, probably the best example I know of a self made man. He built his own house, taught economics and business at the collegiate level for 35 years, and was a fine woodworker. He turned 80 the year I started college. I spent my freshman year at the school he taught at for so many years. I know now that he was in the very early stages of Alzheimer's at the time. I spent too much time accomplishing little during that year and squandered a chance to spend more quality time with him.
2. Bob Dylan opening for The Grateful Dead in RFK stadium
I believe it was the summer of 1995. I was in Washington DC for a journalism conference one of my professors recommended I attend. One of the guys I went to Poland with was living in DC at the time. He had an extra ticket for the show. I didn't have enough money to change my plane ticket so I didn't go to the concert. I'm not a huge fan of The Dead, but I regret not coming up with the money to go to the show.
3. My failure to learn another language
I lived in Mexico for 6 months, I studied in Poland for a semester, and I took two semesters of German in college. In spite of all of these things, I am horribly monolingual.
4. Radio internship
After my junior year in college, I had a chance to do an internship at KFDI in Wichita, KS. KFDI is a country station with a good focus on local news and weather. I needed money to pay the rent, so I didn't do the internship. I'm fairly sure I wouldn't have ended up with a career in any type of media, but I still would've liked to have had the experience.
Overall, I would say that I had a very good college experience . The liberal arts environment was very fruitful, and allowed me to participate in many different activities. I enjoyed being on the radio, singing in the choir, doing lighting design for drama productions, editing the literary magazine. I think I missed some opportunities in the academic arena. I wish I would have taken more theory courses.
