Eric Holder knows a thing or two about introspection. In his current role, companies tap the former U.S. Attorney General to ask difficult questions and help businesses improve everything from diversity to how they work with foreign governments. With the democratization of information and the rise of social media, today's leaders and companies can no longer hide behind a great PR team. According to Holder, "Companies can always be introspective in the same way that we can be as individuals and ask tough questions of ourselves or as corporate entities. What are our strengths? What are our weaknesses? How can we do better?"
