I do have a living hero, and he is Elon Musk.
Has anyone noticed the parallels with Schwarzenegger, and the differences?
When Arnold was a young athlete, someone asked him "so what do you want to do with your life?" He said: "I'd like to be a bodybuilding world champion. Then I'd like to become an actor. Then I'd like to do politics."
He nailed every single one of those goals. But please notice those are the ultimate goals of the individual ego (more precisely, of the male ego): physical power, fame, money, and political power. He's basically Conan in real life.
Now, Elon Musk also made a list of the most important issues to solve - the ones most important for the planet, for humanity as a whole, not for the little individual ego. We need a clean environment, we need energy, and we need to put some of our eggs in another basket.
And then he went on knocking them off the list one by one. First PayPal, to achieve financial independence. Then Tesla Motors (good for the environment), Solar City (energy), and SpaceX (Mars colonization). And he's willing to risk his own life to achieve those goals.
I've no doubt, Elon Musk is up there among the greatest. If he makes it to Mars, one day kids will learn his name from the history books.
