Admittedly, I am an old guy. I am 26, just finishing my second year of med school. 9/11 happened when I was two weeks into my freshman year. I loved college and had a fantastic experience. I played a varsity sport in college, soccer, and competed in national competitions as a snowboarder, so I was pretty busy in addition to my academics as a college student. I also had a girl friend, and belonged to a fraternity, so my social life was full.
But even with athletics, the girl friend, and the frat, I studied hard. I was a singer in my college acapella choir. I did not play video games, or watch television, I went to virtually every class, because I calculated how much I was paying by the hour for each and every class. I made friends with my professors. I cut the useless waste out of my life, but went to the keggers and dances on Friday night and really enjoyed the social life of college.
Set goals, have alot of fun, work hard, and usually it will work out. It did for me.
