Sisyphus is everywhere.
Or more specifically, being loved and love, both of them, simultaneously stimulate self-control. That’s where the magic happens.
Movies are not lying, but they didn’t reveal the process of how self-control painfully works. Probably, Twilight showed — The vampire instincts kicked in, but love allowed her to control the wildness with reason. It was an intense struggle — one side represented the innate nature of a vampire, to hurt; the other side was the eagerness of acquired, to love.
It’s a struggle, a repetitive practice. When it comes to a summit, it’s a rebirth — an absolute joy happens.
Unfortunately, lots of movies didn’t reveal such a vital rebirth. They present that love has magic, but like a fairytale, which is enjoyable yet lacks energy. It gives people the wrong image that pivot happens suddenly. Life works like Sisyphus, in a repetitive development.
