My blog post is a more detailed expression of a sentence that starts with "my personal experience". I think that's fine.

And of course I read the article. That's why my sentence explicitly says "satisfied or very satisfied" whereas the text you quote only selects the "very satisfied". One can imagine that if I had only linked without reading I could not possibly have guessed 81% correctly either.

I'm not saying "just stop being depressed". I'm questioning that any significant portion of the population is depressed. I think that's valid.
