Today we're bringing you a A Call to Lead Classic—one of my favorite interviews that I've done at Call to Lead at SAP's annual Sapphire Now conference. My guest is Walter Isaacson. Talking with Walter is always head-spinning and enlightening because he is the foremost expert on leaders who also happen to be the world's smartest people. Walter's specialty is geniuses. He's written biographies of Benjamin Franklin, Albert Einstein, Steve Jobs, and Leonardo da Vinci. He's also a very smart leader himself, having headed CNN, TIME Magazine, and the Aspen Institute. Here are 5 things that Walter said and my team and I found interesting and relatable to all of us as ever-improving leaders: 5:43 - "If you're going to be a disruptor, you have to do like Steve Jobs and occasionally let your reach exceed your grasp."  19:07 - "Making a great product innovation is hard, but what's really hard and important is making the right team who can continue to do innovation." (Steve Jobs, when he was dying, said this to Walter Isaacson.) 25:03 - "The most important talent you need is the ability to see patterns." 25:03 - "If I were talking to somebody coming into a company now, I'd say what are your passions? And I'd hope there'd be three or four or five diverse passions. And then I would say, 'What is the pattern that you've seen by being interested in so many different things?'" 26:49 "Whatever business you're in, you've got to say I'm not in the business of moving lettuce or moving packages or flying metal, [but rather] I'm in the business of applying technology to customer needs."
