Query: Great!

Nice book and very interesting. I have recently read a book,Personal Best - How Ordinary People Achieve Extraordinary Success and How You Can Toowhich has similar themes with this one. This book could be very useful for everyone. The human mind is a wonderful thing, capable of the most wonderful thought processes and ideas. Great and unnerving at the same time, the book is filled with various studies in the field of social psychology. I cannot recommend this book too highly; an entertaining and informative read. This book is also an effective self defense weapon against those unscrupulous individuals who will take advantage our natural responses to influencing events. Good book, I highly recommend this one!
