10% Happier

It's more a re-accounting of spiritual journey than a book on how to become 10% happier. I was wondering about the title...thinking that 10% happier isn't that great of an improvement and is this book really worth my time? 10% happier was just a way the author explained his meditation in an effort to avoid being judged and to prevent others from thinking he was a quack. At the beginning I almost gave up on this book. I thought it would be a narcissistic recounting of a reporter's life. Towards the end I felt I did get an understanding of the steps the author made to improve his happiness.. I am intrigued about mindfulness and this book bears witness it can improve ones life.
