Query: Silly at best, dangerous at worst

It is no surprise that thinking positively, envisioning what you'd like, making goals to reach your dreams, and then working hard to achieve them is bound to engender more success than thinking negatively, being directionless and lazy. That's not a secret, it's just logic. However, this book takes positive, proactive living to a silly, ridiculous level. The idea that the bad things that happen in life happen because a person "attracted" them is arrogant, cruel, and dangerous. And for the people for whom the "secret" doesn't work? The people selling this - and that's what it is; sales pitch - would say that it is that person's own fault because they didn't believe enough. What a convenient excuse. It allows them to utterly avoid culpability or scrutiny. There's nothing new here - just old snake oil in new bottles.
