These three books are among the best I have read in the past several years. Out of Thin Air is terrific reinforcement of what you must do to compete successfully in an endurance sport. Great insights into training. Huge reinforcement of Seiler’s training polarization concept. The Art of Possible is not another formulaic motivational text. It really is a peak performance primer. Chock full of a practical step by step things you can do to achieve flow. Kotler really nails it. It certainly, got refocused. Think Again will getting rethinking and thinking again. Adam Grant is a rock star in my universe. So much great information here to get you thinking deeper.
