Perfectly put, and right on the money. Or, wait. Something. Anyway, this is such a critical point to make to a generation that's being told that following their passion is the only way to true happiness--and then that happiness is a permanent, all-the-time condition, and if it goes away, something's wrong. Instead, as you say, happiness is a byproduct of doing productive work, and all work is WORK at some point. Usually for a long time, before it starts to pay you anything.
Well today it paid you something. Congratulations.
