So took a low end job - internship. Learned about banking and money. Then built a payment system that was better than the available alternatives of the time. Then he took the money he earned from building better mousetrap and bought / founded two other companies that are killing it by making things better than anyone before them. And now starlink.
He's doing exactly what he says, and the world is rewarding him for making better stuff every day.
His words and actions are in complete agreement.
