I’ve heard “rich” defined as not having to work for your money but being in the position of your money working for you.
I’ll go along with that too. However, for me, the process of making my money work for me (investing and managing my business) is fun. I’d like to see it one day go from 50 hours a week to 20, though.
As for worldly goods, where you draw the line between rich and not rich depends on the person. I have no desire to own a casino or 200-foot yacht, but 3,000 sq ft on a half acre with an ocean view and a GT2 in the garage would be nice.
