" When you are an individual contributor, you try to have all the answers. That’s your job—to be an expert, the best at what you do, maybe even the smartest person in the room. When you are a leader, your job is to have all the questions. You have to be incredibly comfortable looking like the dumbest person in the room. Every conversation you have about a decision, a proposal, or a piece of market information has to be filled with you saying, “What if?” and “Why not?” and “How come? "
