I think the list idea can be a helpful guide for a distractable guy like myself. I get off on a tangent and away I go, totally forgetting what was successful the day before. I had "concentration ADD" before ADD was even recognized.

In elementary school, I would start a project, like the teacher instructed, but by the end, I would have found something more interesting to work on, and hand that in instead. I always got good grades, but at the same time, quizzical looks from the teachers.

I didn't even realize I was doing it.
