Congratulations on what you've accomplished through your positive attitude and hard work!
It seems reasonable to me that diligent people with a positive attitude do better in the long run. And as far as I can tell, your positive attitude and diligence were self-generated.
The "scam" is ['researchers,' not you] claiming that what you've done for yourself, can be bottled, distilled, and taught in a classroom, or through millions of copies of a book, or huge speaking and consulting contracts, etc. That sounds good, but seems to not be true, or at least not be based in science.
Sometimes simple ideas need a bit of marketing and "naming" so that we can concretely pin our actions to a concept that we can anchor on.
I may not have had the language of "mindset" then, but now that I have it, I'm more conscious of it and can communicate the idea succinctly. It's making something previously tacit explicit. I think there's value in that.
