Birds of a feather flock together! How many of us have heard that saying?

According to research by social psychologist Dr. David McClelland of Harvard, the people we habitually associate with are called our “reference group.” And our “reference group” determines as much as 95% of our success or failure in life.

Legendary personal development expert Jim Rohn taught that we become the combined average of the 5 people we hang around with the most. Rohn would say you can tell the quality of our health, attitude, and income by looking at the people we associate with most.

So I urge you to ask yourself: What is the combined average income, health, or attitudes of the five people I’m currently spending the most time with?
