I haven't come to a consensus on people who have to-do lists. I personally scribble down on a regular basis a few things I need to get done. Often it looks like what follows:

1. D-Cleaning Tuesday Night
2. Pay Gas
3. Dust
4. Make fun of Geico Commercials
5. Try to show up to work within 10 minutes of when I am due to be there
6. Stop daydreaming about what it would be like to be raised by wolves
   

I had a boss once, who had the most elaborate lists. Parts of her list included multi-colored ink, a shaped marking system that indicated how far along the to-do was being done, she rewrote the list every other day and then she kept a notebook where she taped the list to a page and added any comments so she could go back week by week if need be to reference. What I took away from this experience was that no matter what her kids did they were going to dissapoint her.
