[57 min 56 sec] How does effective leadership create a work environment where new ideas and risks are embraced and failure is educational? In this keynote session from the 2010 All-Alumni Conference, Zynga Game Network CEO Mark Pincus shares his take on the Haas School’s defining principle of “confidence without attitude.”

From years of playing soccer, Mark gleaned key lessons about being a successful CEO. He learned to value teamwork and reliability, with everyone pulling their own weight, over one or two star players.

As the companies he led grew, Mark realized that keeping a growing team productive would be a challenge. His solution? Make every employee “a CEO of something.” By giving people big jobs — so big that there’s a hint of fear in the air — Mark created a workplace where people actually have more fun and improve faster.
