There's really only 3 kinds of money.
There's "I don't have to worry if I'll make rent or be able to buy groceries this month" money.
There's "I don't have to think about prices or when I go out to dinner" money.
And then there's "I can take unpaid time off whenever I feel like it, and travel to where I feel like" money.
Past that, everything is just bigger numbers.
It always resonated with me, because (a) it phrased money (which doesn't really matter directly) in terms of outcomes (which do matter directly), (b) it coalesced things down into a few, very different outcome buckets, & (c) it made the observation that in terms of life outcomes, there's definitely a ceiling: unless you're looking for ways to blow money, there's a cap on how much you can reasonably spend.
There are all kinds of projects that are potentially useful but not necessarily profitable. Having more millions of dollars means you could do more of them.
You see people here complaining that they can't go from $500k to $600k and everyone says that they're being greedy. But the dissatisfaction is a lot stronger at that range, and it only goes up when people become millionaires.
I think it's quite important to check that you're eating because you're hungry and not out of habit/greed/pride.
People who want "exactly one million, not less, not more" are less frequent in population than people for whom no amount of money is ever enough.
