When things are going well in my life, the back of my mind gets bored. It runs out of stuff it needs to be urgently ploughing through. When bored, it unlocks anything back there it can get its grubby little mitts on, 'cause hey, why not?
Sometimes that's exactly what I need. I tend to forget why I do some of the things I do, and what massive payoff I think I've been waiting around for.
