This is one of the top 10 all time best business books (so far!) according to the NYT. I have to agree.
This book outlines the classic issue ALL entrepreneurs face. Creating a business which provides a job for the entrepreneur vs. creating a business which frees the entrepreneur to pursue other opportunities and choose how and when they work.
The need for control is one of the struggles entrepreneurs have to overcome. Without dealing with this issue, developing the systems and accountability structure will be severely limited,thus limiting the time available to the entrepreneur.
I would also suggest reading the primer Rich Dad, Poor Dad by Robert Kiyosaki. These books are complimentary and provide guidance from two important perspectives.
