I passed by this book four times, picking it up, and putting it down - three times. It seemed too much money for so little book. Nothing could be further from the truth. If you are someone who can think and read between the line(s) (as many of the exceprts ARE just one line!) then this will be a very fulfilling book for you. If you need a framework to support the observations, then maybe you should get the full book. Either way, it's a wonderful way to spend many a half an hour, reading and re-reading.
