Make Your Life Difficult for Your Body

In order to make your body stronger, you have to make life difficult for your body. In a good work of literature, the novel or in a good movie, something needs to go wrong for the characters in order for the movie to exist. If the character is not confronted with any problems, nobody would want to watch that movie. And at some point, as you exercise, there is an influx of renewed energy and then it's not difficult anymore.
