I used to keep an exhaustive list of ideas, piled on to over the course of several long years of fantasizing what I was going to one day build. I found, and somewhat counter to my expectations, that the decision making process was not so measured as it was spur of the moment. My friend, during a Watts-induced meditation, once mused that decision making is an illusion: in reality, you almost never have enough information to make the “right” decision, so instead you make a split-second decision at the exact moment you need to.
I think these are the powerful ideas—ideas so powerful, they shake you from your sleep, and beckon you to work. These sorts of ideas deserve full state-of-mind alacrity and unbending attention; you’d be showing grave disrespect by casting them to your ideas prison.
