Do not waste your time, do not sit there and mess around. Once you put your hands on the bar, once you started to lift, every repetition counts, every single time you lift that weights, it counts. It is about breaking the rules, not the laws, but the rules. It is all about you going after what you want, achieving what you want, not worry about what anybody else thinks. You want to survive, be strong. You fail, you learn. Keep going and never stop. If it is not challenging enough, you are not going to work hard enough to get it. The exact moment is when your body can take it anymore. That is why only the strong will survive. Do not worry about what society says, it is society things. You decide what your destiny, you decide your future and get there through your hard work. You are going to be so strong and whatever it is you choose to do, you know you can accomplish because all it takes is hard work. Stay hungry, and be the hardest worker in the room. You will survive.
