What to read after The 80/20 Principle?

The 80/20 Principle - that 80 per cent of results flow from just 20 per cent of the causes - is the one true principle of highly effective people and organisations. Astonishingly, though the 80/20 Principle has greatly influenced today's world, this is the first book which shows you how to use it in a systematic and practical way.....The pattern of predictable imbalance underlying the 80/20 Principle was first stumbled upon a century ago by Italian economist Vilfredo Pareto - roughly 80 per cent of the wealth went to 20 per cent of the people. The pattern of predictable imbalance crops up throughout life.....In The 80/20 Principle, Richard Koch opens our eyes to the odd way the world really works. He drives home the truth and power of the Principle through a wide range of examples from business, personal and social spheres. The 80/20Principle is the key to controlling our lives. If we can latch on to the few powerful forces within and around us, we can leverage our efforts to multiply effectiveness. Most of what we do has trivial results. A little of what we do really matters. So if we focus on the latter, we can control events instead of being controlled by them, and achieve several times the results.
