Practice until you are so great at what you do that no one can deny any detail of your performance. Being undeniable means performing at the pinnacle of execution. We often set our standards to just get by well enough to receive a “superior”, or be better than the person next to us, but we should push further than that. Set your standards so high that it dares critics to find a flaw. Push the limits of what it means to be great and live to perfect the details of your demands. This is where you will find the greatness you're looking for.
