I came across a similar idea from a random multi-hour MMO analysis video I once watched. The idea is that most people enjoy working (defined as: spending hours, day after day, doing the same subset of things), but most people are not able to do the work they want to do. Their preferred work is not valuable, and so it cannot sustain them, but it is still work they enjoy doing. The idea came up in an MMO video, because it attempts to make the claim that grindy MMOs are enjoyable to certain people because it is work they enjoy doing.
