Most of the things listed. Masturbation is more or less a side-hobby, if I may be so blunt. Usually done to keep unpleasantness from happening at work, or to control natural urges. Most often just to warm myself under the covers. *laughs*
Writing is my favorite, by far. I used to draw a lot, but due to the lack of a scanner I have no use for it anymore unless I draw the worlds or cities my characters inhabit. Never been able to properly draw my characters, with the minor exception of my main Dark character.
Star Wars is on the list, but so is Star Trek. My father and me used to watch The Original Series every weekend together when it came on. I believe I do recall him and me watching it during his last day's. I suppose it's now a fond memory to just sit and watch Star Trek, because it's so a part of my family life now.
Table-top RPG's are one of my favorites also. I love playing Dungeons & Dragon's whenever time allows me to. It's one of those little things I just can't get enough of because you mainly use your imagination, which I entirely support doing, in creating and living in the world the Dungeon Master creates. I still even have my old dice for when I get back in gear, lol.
I believe the most important one not listed here is Meditation. This, by far, is my favorite thing to practice. Through meditation I learn better control over my primal urges and unsatisfactory uncouncious mechanisms that would otherwise possible embarrese me. It's helped me evolve into the person I am today, straying from the emotional and mental hamperings of my youth. Without it, I doubt I'd be as honest and brave about life as I am today.
But yea...there's other things, but those are mainly it.
