This is a great book. It's short, easy to read, and entertaining. But it's also a very powerful book that will change the way you approach creativity and learning.It's not just about "private writing", it's about how to generate creative ideas and increase your learning and retention of what you read. It's also about how to clarify your thinking. The book has more than enough ideas to improve your life than what you would expect in his 141 page book.I give it an A+ in my rating scale. This is a MUST READ for those who want to increase their learning, creativity and retention.John DunbarSugar Land, TX
