There, I said it. Creative types, regardless of your style or delivered medium, tend to be a little bit "off" in the organization and memory departments. While this is a generalization, I do tend to find that it fits most of the creative's I've met, unless they've already got a person or a team of people managing their time and attention.
This is something that I've had to try to manage myself for a long time, in fact, I'm so scatterbrained that my blog post about being scatterbrained almost didn't get written in a timely manner because I was also juggling other tasks and entertaining some new ideas while I was writing it, and I got taken off course for... say... hours. I'm not proud of it, but it is what it is, and it certainly drives the point that this needed to be written and expressed.
