College was amazing, but a lot of it is just nostalgia. The free time, the late night Goldeneye tournaments with my roommates, going out most Thursdays - Saturdays were all great.
The pretty ladies, playing pickup basketball, racquetball, golf and tennis was really fun. However, not having money is rough.
I actually really liked my late 20s and early 30s when I really started running and had toddlers that loved hanging with their dad was equally awesome in a different way.
I feel like our whole life we think about how great things were a decade prior. That said, I was in college in the late 90s and I think that was peak civilization. Internet existed, but not always connected. No social media. Music and movies were amazing.
