Absolutely spot on w.r.t. "Self-Help" movement. It has become a scam similar to all the Leadership/Marketing/Sales BS. Store bookshelves are full of these sort of books with claims that beggars belief. A little thought will show that there are so many interacting factors in any endeavour that there can be no quick, easy, ready-made and always-true solutions. And yet everybody is sold this juvenile crap and it is further propagated without appeal to skepticism. Any real progress due to actual research is further obscured by turning everything into "sound-bites" because the average person is considered "dumb" and cannot grasp nuanced ideas with assumptions and limitations. This toxic mindset has pervaded our entire society and does not forebode well for our future.
