I work as a Guest Services Director and I also happen to adore Ted Talks. Naturally, I was drawn to this book. Something I always tell new team members is "if all else fails, smile." I purchased this book with the idea that it would make a great gift for my team to hammer home the importance of smiling. Its a short read and what I like most about it was that it uses a fair mix of scientific research and personal stories. It does not simply focus on science, however. It also uses examples from several religions and cultures to show that no matter who you are or what your background is, smiling is an important way of life. In fact, one chapter mentioned Darwin, Christianity, Buddhism, and Muslims, all within a paragraph or two. I enjoyed the diversity of examples.
I do not think I will end up purchasing this for my entire team, however. Instead, I will probably highlight the main points in a discussion. A better book for a book study or book club, in my opinion, is Be Our Guest, by Disney Institute because it gives better application. "Smile" is a great little thought experiement though, and I enjoyed the read.
