“It isn’t that you wake up one day and decide that’s it: I am going to be weak. No. It is a slow incremental process. It chips away at our will—it chips away at our discipline. We sleep in a little later. We miss a workout, then another. We start to eat what we shouldn’t eat and drink what we shouldn’t drink. And, without realizing it—one day, you wake up and you have become something that you never would have allowed. Instead of strong—you are weak. Instead of disciplined—you are disorganized and lost. Instead of moving forward and progressing—you are moving backward and decaying.”
