What makes people want to smile? Why do some people live happier and healthier lives than others? Why do some people constantly smile and always appear to have joy in their hearts? The answer lies in the smile of each person. In this book, David Hanan, Ph.D., dives into how we can learn how to smile more often and smile more genuinely. A smile indeed develops from within you. And even a simple smile can have profound effects. But, it is the smile from the heart that attracts more of the same energy towards you. And, when this happens, people will want to be around you more, follow you, and engage with you more. Be the reason for someone else's smile.
