«Take the bus. We’re buying your brother a Tesla,» Dad said. At graduation, the dean announced, «And now, our youngest billionaire graduate…» My parents dropped their programs…

Not because I had to, but because while everyone was showing off their cars, I was busy building an empire. The applause was deafening. In the audience, I could see tech industry leaders, people who’d known my secret all along, nodding in approval.

My executive team, scattered throughout the crowd, were grinning proudly. As I returned to my seat, my phone buzzed with a message from my assistant. Your Bugatti is ready out front for the photos, Ms. Walker.

Miss Walker, Mr. Musk is on the line. He wants to discuss the satellite partnership. Tell him I’ll call back, I said watching my father’s eyes widen at the casual mention of Elon Musk.
