Much of this book is common sense...but if you are organizationally-challenged like I am, it's a good kick in the butt to get started. I have been following the author's blog, unclutterer.com for some time. This book is a compilation of essays written for the blog, with some additional checklists. I come from a family of pack rats, so I initially found her minimalist philosophy a bit harsh. However, she has a point that if something is sitting in your basement unused...you probably don't need it. I may have to do another great purge soon!
