You are the average of the five people you spend the most time with. You've probably heard that saying before. It's from motivational speaker Jim Rohn. He used it as a way to encourage people to learn and grow from others' experiences, habits, attitudes, and so forth. He wanted folks to seek out and spend time with people of high quality. Unfortunately for most people, this advice can be difficult (if not impossible) to implement. That's because we tend to group with like-minded people, which includes hanging out with friends with similar levels of success.
