There is a book that has been a surprising source of happiness in my life over the past three years. It’s a children’s book that has condensed hundreds of years of psychological research into a book that can be read in less than five minutes.

It’s called Let’s Be Happy by P.K. Hallinan and it sums up all that has been said by William James, Martin Seligman, and decades of positive psychologists and other gurus.

As far as impact on my life and ability to inspire, I put it right up there with Oh, The Places You’ll Go by Dr. Seuss in the Must-Read Children’s Books category.

In today’s episode I share what this book has meant to me and how you can apply its principles in your life.
