Your LifeBook is an interactive journal and workbook designed to support your progress on your health journey. Used independently or in conjunction with Dr. A's Habits of Health , Your LifeBook is like having Dr. A walking you through the Habits of Health, giving you lightweight daily and weekly tasks to move you forward toward your goals. About author(s): Dr. A is a New York Times bestselling author and the tenth physician in the world to be board-certified in critical care. When he saw that traditional medicine was failing to truly help patients change their lives, he left critical care to co-found OPTAVIA and to develop his groundbreaking system, Dr. A's Habits of Health . Since then, he has helped hundreds of thousands of people change the trajectory of their lives and continues to lead a community of compassionate health advocates who believe that the Habits of Health can change the world.
