I'm most of the way through this book and will probably finish it. I've enjoyed parts but there's a lot of fluff in between the enjoyable bits.
Also Rubin has used the word q***r twice already. This book was written in 2009. Use a different word (strange works nicely).
There's so much overlap between her blog and the book. Seriously, unless you're really really interested in reading slightly more in-depth about the Happiness Project, skip the book and search the blog instead. The most important points are there.
