Not the best book in the world, but not the worst either. I did not realize that I had already read a book on cleaning/organization by this author. As a result I spent half of the book thinking, boy this sounds familiar. If you read one book on cleaning/organizing it should be this one. If you have one book to tell you how to clean certain things, I think that this book would be a good investment. I found quite a few interesting tips and tricks that I hope to employ in the future. Cleaning is a pretty overwhelming and depressing topic, this book can help to create a better understanding of where we can get started and where our priorities should be. Frequently within this book Donna mentions that if you do not feel comfortable/safe doing something then a professional should be hired. Honestly I do not think we hear that often enough in our lives! Happy Cleaning.
