I'm rarely bored. Not that it ever happens. I actually seem to get bored when I'm depressed, maybe because I can't think of ways to entertain myself, and it kind of creates a cycle. I try not to get bored though, because that tends to lead to the said depression which tends to encourage me into old habbits and I've had enough addictions in the past to know that I don't want to go down that road.
so, I read, I dream, I hike, I paint, I bug my coworkers with random facts and talk about the dreams I had, I play quiz games online, I search deviantart with the most random words I can think of, I take photos, I upload them, and I try and take joy in even life's mundane things. Generally this keeps me from being bored. When all else fails I go to sleep.
