These sort of stories are always kind of baffling to me, because they always follow the same basic outline. Person gets high-paying job they hate, makes huge sacks of cash, but ultimately decides high-paying job is soulless and destroying them. Person then quits high-paying job and presumably uses leftover fat sacks of cash to start new career doing thing they love. And then their advice at the end is inevitably to completely skip the part where they make huge sacks of cash and just do what you love, despite the fact that it usually REALLY QUITE STRONGLY SOUNDS like the one was only made possible by the residual benefit of the other. This particular one only avoids it through the totally improbable one-in-a-million deus ex machina thing with the piano.
