Short, to the point, lots of examples. Read the book over 2 nights.
Does not deal with hoarding -- although it's mentioned and some not-so-obvious ways are introduced to think about your stuff...."does it need me?" vs "do I need it?" :)
Book's focus is how to organize, but rather than a "one size fits all" approach, there are many "out of the box" approaches.
Deals with visual learners/organizers, people who hate filing cabinets (out of sight/out of mind), people who like to touch things and crave movement (vs simply listing it in a day planner).
It talks to people who have trouble with standard organizational systems, such as daytimer calendars, closed filings cabinets, etc.
Lots of interesting ideas!!!
Will post more info about this book in a reply, later.
