In Chapter 19 of 23 in his 2013 Capture Your Flag interview, author and public speaker Simon Sinek answers "As You Have Been Writing the Second Book, How Has it Felt Differently Than the First?" Sinek finds writing his first book "Start With Why" far easier than writing his second, "Leaders Eat Last." He notes how the first came naturally after years developing the concept in hiw work. It just required him writing down the ideas he had been using. The second book, however, required him to develop a new concept from the start and figure it out while he was researching and writing the book. Simon Sinek teaches leaders and organizations how to inspire people. Sinek is the author of two books, "Leaders Eat Last: Why Some Teams Come Together and Others Don't" and "Start With Why: How Great Leaders Inspire Everyone to Take Action". He is a public speaker, an adjunct professor at Columbia University and a Brandeis University graduate.
