This is an entertaining talk by four-star general Stanley McChrystal who shares what he learned about leadership over his decades in the military. How can you build a sense of shared purpose among people of many ages and skill sets? By listening and learning — and addressing the possibility of failure. What he is teaching is relevant in just about any situation. He is a pretty good story-teller. Some aspects of his talk remind me that in many organisations leadership is networked rather than follows old-style heirarchies. And that relationships rule. And that it isn't easy stuff - this leadership caper.
