Mention mankind's tool use to most folk and they'll visualise cavemen with clubs - but the most valuable tool we have ever had sits right between our ears. This well-researched book will lead you into ways of using that brain-gland better, or perhaps even using it consciously for yourself for the first time ever. This is a great place to start, if you haven't already.Highly recommended.
