When I first joined Facebook, I was working with a team to answer the critical question of how best to grow our business. The conversations were getting heated, with many people arguing their own positions strongly. We ended the week without consensus. Dan Rose, leader of our deal team, spent the weekend gathering market data that allowed us to reframe the conversation in analytics. His effort broke the logjam. I then expanded Dan's responsibilities to include product marketing. Taking initiative pays off. It is hard to visualize someone as a leader if she is always waiting to be told what to do.
