There are moments when we achieve peak performance: An athlete plays a perfect game; a business has a quarter with once-in-a-lifetime profits. But these moments are often elusive, and for every amazing day, we may have a hundred ordinary and even unsatisfying days. Fulfillment doesn’t come from isolated peak experiences, but rather from many consistent good days. So how do we sustain performance, while avoiding burnout and maintaining balance?

In Optimal, Daniel Goleman and Cary Cherniss reveal how emotional intelligence can help us have a great day, any day. They explain how to set a realistic, attainable goal of feeling satisfied that you’ve had a productive day — to consistently work at your ‘optimal’ level. Based on research of how hundreds of people build the inner architecture of having a good day, they sketch what an optimal state feels like, and show how emotional intelligence holds the key to our best performance.
