The biggest factor of success in that all aspects of life involve the practice of discipline. We need to look at discipline like a muscle that needs exercise in order for it to grow stronger. The stronger discipline gets, the better we respond to the situations in our life, and where some we have no control, we respond to it on reflex. The practice of discipline becomes a practice of excellence. Once we put our mind to a goal and we have mastered the discipline, there is nothing stopping us.
