It´s always a crime to divorce a Wittgenstein quote from its context – but I´ll do it anyway:
What we can definitely say today is that happy people see the world differently – and I mean literally, not metaphorically. When looking at the same visual information, happy people seem to see more of the scenery, they have a different scope. And this scope, in turn, seems to enlarge their mental scope, thereby transferring the broadening quality to the metaphorical level – which, at the end of the day, makes happy people e.g., more creative.
