The exact same world can seem like an evil or beautiful place, based purely on how you choose to think about it. And paradoxically enough, changing the perspective (and thus the behavior) of enough people can even change the physical reality of the world for the better. That makes “just changing your perspective” into a pretty powerful tool.
Self-help maniacs (like me) have no dearth of preachers or research that proves one thing one day & another the next. As this article (citing research) points out, I don’t know what the **** I’m doing. More specifically, I don’t know why I do what I do (whatever it is I do!). An entertaining read, nonetheless!
