Dorothy: This was drawn from my own experience. So I "cannot" be wrong because I lived through it myself. And also, i don't intend to harm anyone. Over and over again I point out that I love a lot of Pavlina's stuff, although I'm critical of some of it.
I would have gotten the same bad result from any other positive psychology ideas. Nothing wrong with Pavlina's... It's all great - if you are feeling well mentally.
And of course anything can be harmful. Words are very powerful. If something can heal it can kill to. That's true for everything.
