Martin's book condenses a lifetime of research and experience into a easily digestible and interesting book. It draws on interesting examples from industry, combines with science and research and distills this into practical advice. I've already made adjustments to my approaches in the work place and personal life as a result. This is having a positive impact and I'm strongly reccomending the book to friends and collegues.
Please give it a read. You won't regret it and well worth the personal investment.
