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 I lived a really quiet life with my ex-girlfriend. Would I like to do all that 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, spend insane amounts of time planning my social calendar, going to or organizing/leading social events, and I used to play quidditch.
