You think according to how your culture wants you to think. Culture is a 'box' persons are in. Everyone thinks "inside the box." They very rarely think outside of it.
"Step outside the box" "Criticize your culture" Oh yeah, baby. It's just rhetoric, baby.
These are profound sentiments, but harder to do than it is to say, and even when we say "outside the box," it doesn't mean much. We are trapped in our culture, our box --- like, hmmmmm (let's find a nice one here guys) Um---ants in a glass ant display?
It is much harder to talk about "creativity" than to be creative.
