I have lots of hobbies and enjoy my downtime, too. But I think what matters most is the interpersonal stuff: how we treat others, what we care about and who we make time for.
I like to spend my time trying out new stuff in the kitchen or working on projects.
Books: I just got back most of my books I had to leave behind when I was moving around. What I have is usually a bit of the bizarre or sublime. Think Vonnegut or Palahniuk, and I reread Calvin and Hobbes often.
Movies: Wes Anderson, Q Tarantino, Coen Brothers, and pretty much anything with Bill Murray.
TV shows that need to be brought back: Dirty Jobs, MST3K.
Music: I love pretty much any live music, but I'd prefer an outdoor festival to a cramped club. Rock music peaked in the late 80s and early 90s. I like the folksy stuff and indie rock that is out now, but sometimes I need some Faith No More or Blind Melon.

I mostly look for chemistry when I meet someone new. Yeah, it's hard to define, but I think it requires putting yourself out there for people to see. If their is a sense of connection, I see where it goes.
