In "The 7 Habits of Highly Effective People," Stephen Covey introduces the concept of "principle-centered living." This refers to living in accordance with universal principles that are fundamental to human nature and are based on timeless truths. These principles include fairness, integrity, honesty, respect, and responsibility. According to Covey, when we live our lives according to these principles, we are able to think more clearly and make better decisions, and we are also better able to build strong, healthy relationships with others. Covey calls this approach to life "principle-centered" because it is centered on these universal principles, rather than on our own desires or the expectations of others.
