Two things in particular stood out to me after talking to Sheldon. First, you can be ruthlessly efficient without being a ruthless person. And second, the conversation reaffirmed how important it is to enjoy what you do. Sheldon and his team have built a multi-billion dollar industry leader on the premise that people are the most efficient and effective when they love what they do and care about why they do it. I wanted to understand more about how someone could be so focused on efficiency as a manager and at the same time connect emotionally with their people.
