Again, you&#x27;re stating things people already know (maybe not in terms of marginal utility, but they do). You say you grew up poor, but the money you needed in order to be happy weren&#x27;t millions or billions. It was a lot less. Beyond this, more money doesn&#x27;t mean happiness, which is what people mean when they say it... but you already knew this, didn&#x27;t you?<p>If the return in happiness&#x2F;peace of mind you get beyond $75K (or whatever number) is close to nil, those all-nighters and cheap noodle lunches are simply not worth it by definition. Unless you <i>enjoy</i> living like that, of course, but the implication is that most startup founders don&#x27;t, it&#x27;s just stuff they do because they see the gold pot at the end.
