Happiness is relative, and your personal happiness likely settle down to the same place. So if you get a huge windfall (millions of dollars), you will be happier for a short term, but ultimately, your happiness will fall back to your normal levels. At that point you have different concerns, but you still have concerns.
"At that point you have different concerns, but you still have concerns."
Concerns differ in terms of criticality. "I lack motivation because I don't NEED to work" is a very different concern from "I work 60 hours a week and still can barely put food on the table". The former may seem like a major concern when it's happening to you, but from a non-relative perspective, it's still much less serious than the latter.
