This was one of my favorite books read in 2017, I strongly recommend reading it. Andrew Carnegie's major motive was making men more useful to themselves and others. He said that making better men is a greater motive than making money.
Read this book because Paul Akers said Eat Move Sleep motivated him to make healthy changes in his lifestyle and led to him writing Lean Health. After reading this book I made several small changes that have had a positive impact on my productivity and lifestyle.
