From 70k job to $5 million a year

I have a friend. He's about 27. He makes more money than most doctors in their 50s. Now, he started out his career in big corporate, like management consulting. He was an accountant at Deloitte. He worked in their tax department. But after about two years, he quit his job and went and started his own firm. And since he's done that, his income has gone up by about 20x. So, at Deloitte, straight out of college, he was making, like, 70 or 80 grand a year, which is actually, like, really good for somebody straight out of school. But when he quit his job his very first year, he did about $800,000 in revenue. His second year, 1.7 million. His third year, 3.1. And now he's in his fourth year running his own business, and he's on his way to probably doing about four and a half or five million dollars this year.
