i used to argue with my sister about stuff like this (she's a life coach) -- surely there is a limit in the physical world for positive thinking -- no she says, there is not -- so, i say, if you're a prisoner in a cell... can you positive think yourself the fuck outta there? oh the look on her face, priceless! I don't think she'd ever thought it through -- now just refuses it and claims that I'm the problem and not her childlike premises
