i would go back to first week of college and take it more seriously. i didn't get kicked out or anything, it's just a huge pain to rebuild a smouldering GPA.
i would work out and eat a little better. it's baffling when you feel and look good, but doc tells you your cholesterol(sp?) is too high. that's like the track star dropping dead at 28 and the chain smoker living to 100. (unfortunately both have happened)
i would bed more girls. found a dedicated, long-standing, monogamous relationship in one go, and i'm 20 now. wouldn't trade it now, just wonder what it would be like. grass is greener, and such.
i would have taken the NYPD test earlier. now there's a hiring freeze, and idk when i'm going to get my phone call. stressful when that's ALL you want to do.
i would get into at least ONE fistfight. there have been too many conflicts i have ended simply by being angrier and louder, or walking away from. i wish i had inverted that kid's elbow in high school.
