My PDF experience this year was bittersweet. I had a lot of fun, but I also suffered a lot from social anxiety. This guy I just met was good looking or seemed like he might have a problem with me (or worse yet, both), and so I'd sit in the corner and feel sorry for myself. After the event I mentioned it to my wonderful campmates from Barrel of Fun, and many of them said they'd experienced the same kind of self doubt as I had. Something about that was so reassuring that my social anxiety has all but disappeared since then.
Doing Crucible and Deathcon at the same time was a huge part of this too. I always come back from DR with great ideas, I think because I get to bounce off so many creative people there and we all cross-pollinate each other's unconscious minds. But the amount of great ideas coming off that weekend wasn't twice but more like three or four times normal. And while it's trickled from sudden bursts of insight to more of an on-demand kind of thing, that fountain of ideas hasn't turned off completely. I think as long as I tend it and drink from it regularly, it never will.
I've lost most of my will to watch hours of TV or to overeat. I'd much rather read or write something, most of the time, and when I do watch TV it's usually something interesting rather than something diverting. I've already had enough entertaining television to last a lifetime. I've also been having a much easier time with my temper because now I have perspective about what matters and what doesn't. What matters is what allows me to express myself and what doesn't, what helps people and what doesn't. But that leaves a whole lot of things I can just avoid worrying about. I do keep having to remind myself that money is not one of these things, because my day job now seems like an annoyance getting in the way of my real work. I always knew it was that way, but until recently I had no idea how to make self-employment as a writer actually feasible.
