This is an excellent book. If you want to get new perspective on your lifestyle and habits, both professional and personal, you won't find a better book. The authors deal with the context of people's lives and offer prescriptions that will move them toward the use of energy and time that will give them the lifestyle they desire. It is a very down-to-earth approach without any preaching or condescension. I can't recommend it enough. Buy it and improve your life.
