what does "private sector" indicate?
What I learned in the private sector affected me as much or more as my time in government, and the rules reflect that. They have been enhanced by continued note-taking, and in this book, they are augmented with stories and anecdotes. In some cases, Rumsfeld’s Rules are the product of errors I’ve seen others make; others are lessons learned the hard way from mistakes of my own. As such, they represent a unique and personal distillation of wisdom gathered over the course of a lifetime.
