The owner of the pizza place that my friend works at is extremely rich. He owns three successful franchises in town and makes great investments.
He started from scratch. He got a job at that same pizza place when he was 16. His very first job. By the time he was 24 he had saved enough money to purchase his own franchise.
Now, at the ripe age of 45, he lives in his mansion with his ten cats and drives the brand new Z7 Corvette that he paid for in cash. And he still goes to work baking pizzas because he likes it.
