That's it I just finished and even devour this book! I believe reread more than once because it is full of good advice but not easy to implement in a single reading. I have not yet begun the challenge of not bitching for 21 days ... because even though I'm not a big raleuse, I realized it happened often to me that I thought ... It is a book that everyone should read, grumpy or not! It is pleasant thanks to the many illustrations, anecdotes, exercises and quotes.
