"Smart people surround themselves with smarter people. One of my favorite adages is never to be the smartest person in the room. If someone is smarter than me in a particular area, I will happily work with them and take the opportunity to learn from them. Ego is not an obstacle for me, and I am happy to recognize and praise exceptional talent. Ewing Marion Kauffman said, 'Hire people who are smarter than you. In doing so, you prevent limiting the organization to the level of your own ability, and you grow the capabilities of your company.' That piece of advice has stuck with me, and I believe this mindset fits Amazon's Leadership Principles very well, particularly when it comes to hiring and developing the best."
