If you want to live a life of purpose, build good habits and achieve your goals, there is one skill that is more important than anything else: Self-Discipline. Self-discipline is not about punishment, it’s about self-respect. It is not about being inflexible, but about living your best life. It is the superpower of focus in a world of distractions — allowing you to overcome procrastination, excuses, bad habits, low motivation, failures, and self-doubt. With it, you can stay on track with your values and goals even through the times when you are least inspired.
