I also collect hobbies. My newest hobby is baking bread. I'm really getting into it. My sourdough starter is like a pet to me...
Also lots of non-fiction by Carl Sagan, Oliver Sacks, Daniel Dennett, Michael Pollan, Steven Pinker, Mary Roach, Michael Lewis, etc.
Movies: Recently I've really liked The Martian, Ex Machina, Trainwreck, Birdman, Interstellar...Inside Out. In general I enjoy stuff by Kubrick, Tarantino, Lynch, etc.
Food: I love to cook and am not afraid to take on most any recipe. I guess my favorites are Indian, Thai, Mediterranean, and Japanese.
Music: Stuff I've been listening to a lot lately would include Vampire Weekend, Arcade Fire, Animal Collective, Beach House, The National, Air, Yo La Tengo, Radiohead.
I'm not afraid to blast some Taylor Swift or Lana Del Ray though... I could go on practically forever about music.
Podcasts (makes things like cleaning and driving much more interesting)
The human mind and all its crazy geniuses and flaws.
How I can make my own meaning in life; in a way that actually feels meaningful.
How twelve musical notes and a relatively limited amount of rhythms and song structures can make up such an amazing variety of music.
