The 80/20 principle is the cornerstone of results-based living. Read this book and use it.
Richard Koch delivers some sharp cross-disciplinary comparisons and knows his onions on both sides of the business/science fence. Koch's feet are firmly on the ground.
Cogently, entertainingly and often controversially, [Koch] draws parallels between the natural universe and the modern business world. Persevere with Koch's often elegant through processes and you will look at your business quite differently.
Time Management is not about organizing your daily tasks, it is about organizing your essential daily tasks, and dumping the rest. Koch has made millions from this - a bestseller based on just one idea - proving that it works.
