You
Yes, you. “But, wait… why would this list include me?” If you paid attention, you’d see that I wrote, “whether from a movie or game or from somewhere” From somewhere means that it could be from life, and that’ll include you. So why you? Why should you be include in this list? Because you have the potential to be the villain. You might say, “Well, maybe I could take a bite off this choco bar” or “I’m lazy! I’ll just do the workout tomorrow” So in a way, you’re being a villain in your life. You’ll even do harmful things like smoking, drinking too much beer, doing hazardous diets, etc. The dark side within you is the villain
So you can motivate yourself to workout by being the hero. You can do things that benefit you, and you can thwart away the dark side. See?
