Self-disciple is one trait separating successful and unsuccessful people. It is the one trait that separates healthy and unhealthy people. It is the one trait that separates couples with successful relationships from couples who struggle in relationship. Self-discipline allows us to focus solely on what we have to do to reach a goal. It is the letting go of all other choices that interfere with the pursuit of the goal. The question that self-disciplined people ask when confronted with multiple choices is, “Which choice takes me closer to the goal I am pursuing?”
