To be the best, whether in sports or business or any other aspect of life, it’s never enough to just get to the top; you have to stay there, and then you have to climb higher, because there’s always someone right behind you trying to catch up. Most people are willing to settle for “good enough.” But if you want to be unstoppable, those words mean nothing to you. Being the best means engineering your life so you never stop until you get what you want, and then you keep going until you get what’s next. And then you go for even more.
