This book had really negative reviews on Amazon - people saying it was too obvious, too repetitive, very Americentric - but I decided to read it anyway, since I'm focusing on simplicity and frugality in my life at the moment, and I figured that with 500 tips, there would be at least one useful one. And that logic proved to be right - the vast majority of tips were things I do anyway (make my own meals, use the library, go for nature walks, etc.) and there was a lot of repetition, but there were a couple of tips that I liked. In fact, I just massaged my face with honey, which was one tip, and my face is all soft now, just like it said. And I like the idea of going on a spending fast. Those were the two tips I liked, out of the 500 - so I then returned the book to the Kindle store, to get my money back, because it's not a book I will return to.
