Not to devalue your point, but if you truly were spending (10 + 3*75 + 20)*30 + 150 per month (so a total of 7800 USD) and you invest it in an index fund getting back 5%, you’ll have your million in 10 years. 8 years at 10% which is the long-term growth rate of DJIA and S&P 500.

You’ll still never be the richest person in the world, but if you truly were burning away that much money, you could make decent dough just from investing it passively. In 30 years you’d have like 15 million, more than enough to retire.
