I need boredom. Sometimes I forget that, but it's absolutely essential. I always talk about how I work too much, and those that know me well will remember stories of how I loved match class in high school because I was so extremely bored I was able to do massive amounts of writing.
Tonight, I turned the TV off and instantly was able to start writing better and faster than I have in weeks. I don't know what's special about tonight versus any other night I've done the same thing... but tonight, I'm bored. It's invigorating.
