While there are thousands of books about leadership, and while most of them are excellent reads, there are very few - if any - that can show you, with real reliability, how to improve your own leadership performance. This is that rare book. We spent years researching leaders around the world to understand why the best are the best. Along the way, we discovered something amazing: why leaders fail. Leaders fail not because they're bad people, or because they lack the personality traits that make for good leadership. They fail because they have a philosophy of leadership that sets them up to fail. If you understand your own philosophy of leadership and make changes where they are needed, you will improve your leadership performance. It's that simple, and the science is right here.
