There is never "enough" income, depending on your tastes and expectations. I read and enjoy and lot of MMM, but he's absolutely off his tits about some things (cars, groceries, real estate) for the lifestyle I ENJOY leading. For me and my wife, it isn't about having "the best" car, or the biggest house or anything like that, it's more that we enjoy driving cars that are - wait for it - fun to drive. Enjoyable. I have a buddy who makes a good income in the high $100k's, and drives a fucking Subaru Forester. Nothing wrong with that. Nothing wrong with the car, really, as it simply shows he's not into cars (or fun). If you don't mind driving an economical little car that isn't fun to drive, so be it - but I enjoy it. I also enjoy $600/night on hotel rooms when I travel and flying first class (because I can't afford share of netjets... yet). That doesn't mean we don't have enough now, we do and are very fortunate. But, the pull of always wanting more is there, and it isn't driven by status - it's literally just the appeal of leveling up. It's fun, and keeps the business moving especially when you're relatively young (33). My old man retired with practically no money, my mom and dad never go on vacations (except in their Outback to Colorado, etc) and don't spend a ton and are legitimately contented. I'm happy for them, and envious that the lifestyle they enjoy leading is so affordable. Warren Buffet acquires money for the shear thrill of the acquisition - the money itself is largely irrelevant, as he doesn't enjoy fancy vacations, fast cars, or massive homes either. Everyone's perspective is going to vary wildly, and ultimately, however happy you are at whatever income you're at decides how much is enough.
