He was motivated to help others with their psychological or emotional challenges by his own life journey, which started with sexual victimization as a young child. Severely depressed, he did not have the skills to make friends and was badly bullied. At the age of ten, Dr. Berry made a vow to himself to learn to understand the behaviors of others in order to change his life. He ultimately studied psychology as a college student and received his PhD. The Book of Life is the product of over eight years of college and four advanced degrees, as well as thirty years of practice in his field. It contains the principles that guide the author's life and that he teaches to his clients. It is the first book of its kind to combine both science and spirituality into simple, easy-to-understand principles.
