Robert Caro's biographies, The Power Broker about Robert Moses, and the series on Lyndon Johnson are among my favorite books. His explanation of his writing process is fascinating. Especially his thoughts on how he prepares to write a book, outlining, and how he counts and charts his words written at the end of every day.
This is my first reading of a Seth Godin book, enjoyed in very much. It has insights on a variety of topics. His thoughts on the decision between better and safer was a significant ah-ha moment for me. Understanding that most people are looking for safer and not better is an important mental model I have incorporated into my thinking.
