What is the Pareto Principle?
The Pareto Principle, also known as the 80/20 rule, is a phenomenon in which 80% of outcomes are driven by 20% of causes. It's named after Italian economist and sociologist Vilfredo Pareto, who observed in the early 1900s that 80% of Italy's land was owned by 20% of the population. He witnessed a similar pattern in his garden, where just 20% of pea pods contained 80% of the peas.
The Pareto principle was later popularized by Joseph Duran, a U.S. management consultant. Since then, it's become a popular concept among those promoting time management and productivity hacks.
