One of the most important ideas that you should be aware of that has the potential to change your life is the concept of Less is More and the 80:20 rule. The 80:20 rule is also referred to as the Pareto Principle after the name of the famous 19th century Italian economist and philosopher called Vilfredo Pareto. There are two wonderful books I highly recommend that are devoted to this subject called the 80:20 Principle by Richard Koch (see https://richardkoch.net/2012/11/the-8020-principle-2/ ) and The One Thing by Gary Keller and co-author Jay Papasan ( https://www.the1thing.com/ ) that go into detail about the power of this principle. This article provides an overview of the key elements of the principle.
