A lot of people on these dating sites have a laundry list of hobbies that I could never hold a candle to, like "I love camping, hiking, and going to the moon on a regular basis" and I just haven't done any of that. In my 20s and early 30s I lived a really quiet life with my ex in a house in the south. We made enough money to live and that was our life. Would I like to do all this crazy stuff? Yes, absolutely I would be open to trying most if not all of that.
That being said, my favorite things to do in the past 3 years in NYC have simply been to go out, meet people, and have fun in whatever manner presents itself.
If you want an idea of some of my life, I am currently learning how to swing dance, learning yoga via home video, study body language, occasionally peruse personal growth materials, draw comics purely for fun, try to walk 3 miles a day (weather permitting), spend insane amounts of time planning my social calendar, going to meetups, and I used to play quidditch.
