A little voyeuristic. Basically a collection of to-do lists grouped in categories: daily, life, new year's resolutions, dream jobs and bored at work, soul mates, relationships, sex, obsessive compulsive, health and sickness, family and friends, happiness and hates. The author/collector does a short introductory chapter, and then a one-page introduction to each chapter. Each to-do list is presented as a pdf type image, so it looks as it originally did -- often very scruffy. Accompanying each to do list is a short summary from the person -- name, age, location, what the list was about to them. The appendix at the end is interesting: some statistics about the listmakers, based on a survey of 600 who responded on her blog. Many more women than men, but that may be a function of who reads her blog / was willing to respond. Pen and paper overwhelmingly over electronic (2006); overwhelmingly enjoy making lists; majority of people cross off items as completed; half add items to the list after they've already completed them for the credit; feel that the lists make them more productive; a minority admit to writing lists in code; life is better because of lists; a minority make "don't do" lists; only half feel it improves their love lives; only half itemize their sexual past; and a minority admit to obsessive list-making.I went through this quickly and enjoyed it. I wondered about people who held onto lists for so long, and also that they were willing to mail them in to this author. I liked the idea that one cognitive behaviorist gave to one of the list makers: to estimate how much of some thing they planned to do in a day, and then next to it, record how much they actually did. I guess that would be my takeaway.
