From the bestselling author of Is Work Killing You? and The Little Book of Stress Relief Dr. David Posen comes a book about listening to your body, understanding your mind, and making better choices in your life. For over thirty years, Dr. David Posen has counselled patients suffering from severe stress, anxiety, and depression. Over that time, he noticed a pattern. As our lives have become faster and increasingly fragmented, many of us have become disconnected from our true selves. We've become round pegs trying to fit into square holes. And when we try to be what we're not, the result isn't surprising: we become unhappy, burnt out, and in extreme cases, depressed. Using a holistic approach that combines elements of physiology, psychology, and philosophy, Authenticity teaches readers to identify, acknowledge, and accept their true selves in order to make better, more informed, and realistic life choices. Drawing on real-life examples from his experience in stress management, Dr. Posen has identified five common sources of anxiety and unhappiness: personality type, relation to time, sleep patterns, passions, and values. For each of these areas, the solution is surprisingly simple. We must learn to live in a way that is authentic and true to our unique selves; we must live in harmony with who we truly are.
