"Because he's the hero Gotham deserves, but not the one it needs right now, so we'll hunt him. Because he can take it, because he's not a hero. He's a silent guardian, a watchful protector, a Dark Knight."
Jonathan Nolan, The Dark Night
A Product Manager is whatever the customer and company needs.
Batman is one of the best because he is humble, smart, doesn't care for fame (Not talking about Bruce Wayne here :P ) and seemingly invincible because of his endless willpower, discipline and stubbornness. He beats every villain, always stands up even after he got beaten and even managed to defeat the best even though he is just a mortal human.
He shows us what incredible achievements willpower, intelligence and virtues in a character can do. We can grow above ourselves and become every day a better version of yesterday. This is what live is about! Challenge yourself and continuously grow by leaving your comfort zone.
