What is productive paranoia and why is it so important in leadership? Many leaders think that optimists are the best people to lead companies, but in fact the data says that optimists have a much higher chance of failing. Instead, the leaders who always ask 'what if, what if, what if?' are the ones who build enduring great companies. You can only learn if you survive your mistakes, and the only way to survive your mistakes is to be constantly on the lookout for things that can impact your plans. In this episode, Brad and Kevin talk about the concept of productive paranoia, and why it's a critical leadership tool.
