The 80/20 Principle

a book by Richard Koch — the secret to achieving more with less

A majority of our time and effort is spent inefficiently on things that produce very little reward. The Pareto Principle has implications for every area of life, and helps single out the most important factors in any situation.

the majority of our time is not spent efficiently

Economist Vilfredo Pareto founded a principle specifying that in almost any area, a mere 20 percent of the effort produces 80 percent of the reward. This means that a majority of our time is not spent efficiently, and if we refocus on the 20 percent that is producing the most results, we will see a tremendous boost in efficiency. This simple concept can be applied to any sphere of life, ranging from business to friends and quality of life.
