I never really was able to summon the initiative to read a book about organization etc.

But I have learned that short term accountability is really effective to me. The system that has evolved and seems to be working okay is:

Every week I have a meeting with my boss to talk about ongoing projects and what specific tasks I am going to complete on which dates in the coming the coming week.

Every night after the kids are in bed my wife asks me if I have completed everything on my list for that day. (She doesn't need to know what they are)

What works for me is that I'm not overburdening any single person with what's traditionally considered personal organization, and my boss isn't micromanaging me, and doesn't have to follow up with every task. But, I'm still getting the micro accountabilities that give me that sense of urgency because I don't want to tell my wife I didn't succeed.
