Formula for/to calculate independently wealthy

Memorable quotes from Gordon Gekko:

"I'm talking liquid. Enough money to have your own jet. Enough money not to waste time. Fifty, one hundred million dollars. A player."

"You see that building over there? I bought it three years ago. My first real estate transaction. I sold it ten months later and made $800,000 profit. It was better than sex. At the time it was all the money in the world. Now it's a day's pay"

If you replace real estate with poker, I think Phil Ivey used the last quote on ESPN regarding his poker career.
