Elon Musk launched a Tesla into space. Unless you’ve been living under a rock, you also know he named the mannequin driver Starman. It all seems like a ridiculous PR stunt, but it wasn’t. At least not in the sleazy way. What Elon did was share his sweeping vision for the future in a way that was guaranteed to go viral. You might not have billions and a major corporation backing you, but you can take some profound lessons from Mr. Musk.
