I have read quite a few organizing books and this one is not my favorite. It is funny and can be quite motivational for a beginner but not as thorough as some. Being a professional organizer I read alot of different books and although Don Aslett is very successful this one isn't the best choice.
This is the best, best book if you are struggling with mounting piles of stuff and paper at home. I read it once a year to get encouraged on how to tackle stuff and make it work for me rather than get overwhelmed by my piles.
