I've had a similar thought of this regarding one hit wonders. So many of them hit it big on a single song and they end up thinking that the hit was because the people like "them" when a lot of the time, it just hit the cultural zeitgeist at the right time or was used in a commercia/tiktok. I often think if that happened for me, I'd try my best to milk it and then dip. You might only have a few hundred thousand dollars but save it and go back to what you were doing before while still making music on the side.

The best example I've seen of this is chamillionaire. He had a string of 3-5 hits but diversified and has stayed wealthy while many of the people in a similar vein are broke.
