After 15 years leading the parent company of KFC, Pizza Hut, and Taco Bell, David Novak wanted to help others become better leaders. He believes the key is to put learning at the center of everything you do, whether you’re an entry-level worker or a multinational executive. Novak outlines three main areas for learning: from your own life experiences, from the people and situations available right now, and from the habit of curiosity. Above all, he says the most effective leaders turn their learnings into action, something that takes insight and practice. Novak’s new book is How Leaders Learn: Master the Habits of the World's Most Successful People.
