First published in 1989, Stephen Covey’s book “The 7 Habits of Highly Effective People” has sold more than 40 million copies worldwide and is widely regarded as one of the most influential self-help books ever written. By all accounts a down-to-earth, kind man of intellect and faith, Covey built his teachings around the concept of nurturing win-win relationships — the idea that we will never succeed long term in any endeavor unless we strive, in all we do, to make sure that the people we work with benefit as much as we do.
