willpower

There are thousands of available diets. But many people pick one to try for a short time, only to quit soon after. Hundreds of thousands of businesses were started in 2015, but many of those have already closed their doors. And there are 144 professional sports teams within the five major sports, but only five champions. Of course, there is no perfect diet, or business, or sports team, but there are those who will put in the necessary work to win.
