The ancient Greeks' idea of fate wasn't always romantic. Not unless you think answering the riddle of a giant Sphinx to become the leader of a land and eventually having kids with your own mother is romantic. According to the Greek tragedians, fate is downright diabolical.
But somewhere down the line, fate took on a happier, more inspiring tone. Movies and stories about people overcoming insurmountable odds because of some fateful birthright are everywhere. I mean, what's the tale of Harry Potter about if not fate? I'm pretty sure there are tons of kids out there in the world who are still waiting for that letter to Hogwarts to give their lives meaning.
