At times it can feel that being successful as an individual requires the defeat of the competition. Shawn Achor joins us to talk about why that falls under what he calls “small potential” thinking – and about why achieving “big” potential requires working with those around us. His new book is called “Big Potential: How Transforming the Pursuit of Success Raises Our Achievement, Happiness, and Well-Being” (Currency). He speaks tonight as part of DMA Arts & Letters Live! at the Dallas Museum of Art.
