feel the burn, they are ready to give up. By applying the 40% rule, you begin to realize that you have unlimited potential. The key to tapping into this reservoir of potential is to ignore the voice in your head telling you it’s time to throw in the towel, and push through the pain. When you truly believe you are capable of more, you will shatter your pain points, which builds confidence and mental toughness. For example, after doing ten pull-ups, you start hearing the voice in your head saying you are too tired, too weak, and too sore to keep going. But if you take a break for a few seconds and then keep going, you’ve just proved to the voice in your head that it was wrong! You then take another short break and do one more, and before you know it, you’ve done 20 pull-ups. You had to slow down to achieve it, but you ended up doing 20 more pull-ups than you had first anticipated. Belief is one of the key ingredients to improving your self-discipline. Success becomes your reality when you believe you can do more, and it allows you to break down the limitations you have placed on yourself. Self-discipline is about endurance. When you are determined to continue but your mind is telling you to quit, you will build a resilience that will make you unstoppable. The mind becomes our best friend when we believe in ourselves, but when we have accepted the narrative of failure, it becomes our worst enemy. The next time you feel like giving up, use the 40% rule to empower yourself. I want you to take a moment and think about this: even though you know you are not fit enough because you haven’t practiced, you decide to run a marathon. As you are running, your legs start feeling weak, you can’t catch your breath, and at this point, you decide that running a marathon when you were not prepared wasn’t a good idea. It probably would be wise to give up and save yourself the agony it would cause if you completed the marathon. But if someone wanted to cause you harm and you were running for your life, you would keep running regardless of how tired you were, because if you stopped, the person chasing you might kill you. The point is that most of us are ignorant of what we are really capable of. We have become complacent, we put on 10 Ibs., buy a larger size, and convince ourselves that our stomach isn’t protruding; or we work at a job we hate but the bills are getting paid, so we tolerate it. When we don’t challenge ourselves, it is impossible to get a glimpse of our true potential. The people who master discipline have done so because they have chosen to be extraordinary. Outside of the excitement and camaraderie of watching sports, one of the reasons we love it so much is because we are admiring the players’ ability to master their craft. If we were to invest the same amount of time we spent sitting
