Pareto's law

Hi everyone good morning, since long time i've been thinking share about my favourite books so let me share today one of them about the 80/20 principle or the other name is Pareto's law. The book writren by Richard Koch
We tend to assume that 50 percent of causes or inputs will accaount for 50 percent of results or outputs. That seems to be a natural, almost democratic expectation that causes and results are generally equally balanced. 50/50 insight is one of the most inaccurate and harmful, deeply rooted, of our mental map. For example 80% percent of the world's wealth is possesed by 25 percent of the world' people, 80 percent of world's energy is consumed by 15 percent of wolrd's people. The most firms 80% of profits come from 20% of clients. The princilpe applies oue life, our social world, and to the place where we work. The book's message is we dont have to work hard, we have to learn concentrate on what is important, on those few objectives that can give us more productive or profite. We have to learn work right places and right time. I hope you'll like this book and when you read it please share with your opinion
