Small nitpick: I think the reason self-help has little effect is that most people don’t apply it, not that they apply it and nothing happens.
I think a sizeable portion of people do things like daily affirmations.
But even for applied self help there are often effects but the effect are neither that the person ends up as a billionaires or homeless.
