Teenage | Millionaire

He’d started at fourteen, coding by the light of a desk lamp while his parents thought he was doing homework. His first "big" win wasn't a million dollars; it was the $20 he made selling a digital skin for a game. But that $20 became the seed. He didn’t buy sneakers or a new console; he opened a brokerage account with his dad's help and started learning the language of the S&P 500.

As he drove away, he realized the money didn't change the fact that he was seventeen. He had a million dollars in the bank, but he still had a curfew, a chemistry test on Monday, and a lot more to learn than any bank balance could teach him. How video games turn teenagers into millionaires - BBC

He bought his mom a house first, just like the creator . He paid off his sister’s college tuition so she wouldn't have to carry the debt that kept so many people awake at night. But at school, he was still just Leo. He still ate the same mediocre cafeteria pizza and worried about the O-levels.

She looked at him, then at the car, then back at him. "Leo? I heard a rumor... about that app of yours." Leo smiled, grabbing the bags. "It’s doing okay, ma'am."

Leo laughed. "Wouldn't miss it. I still need to know how the real world works."

Leo sat in the back of Mrs. Gable’s economics class, his thumb hovering over a "Sell" button on his cracked phone screen. While his classmates were debating the merits of supply and demand curves on the whiteboard, Leo was watching a real-time graph of "EduSpark," the peer-to-peer tutoring app he’d built in his bedroom.
