The problem I have with the "law of attraction" (aka The Secret, if you remember that book) - I mean, aside from the obvious total lack of any known physical mechanism by which it would work - is that it essentially states that if you don't have what you want or need, it's your fault for not wanting it hard enough.

So.. a kid dying of malnutrition in a third world country - can they have everything they want too if they just wish harder? What about someone watching their wife die of lukemia? Is it their fault for not really wanting them to be better harder? What about everybody who died in Nazi concentration camps in WW2 - did they just not want freedom enough?

There's nothing wrong with the idea of aiming high, and challenging yourself to get what you want out of life, but to say that all you have to do is want it hard enough and it will happen is not only nonsense, it's a cruel victim-blaming worldview.
