I think there is too much emphasis in our society on thinking outside of the box. I know what you are thinking, I have finally stepped out of my artistic clothing into the dry world of science forever. You would be wrong.
I am not shunning creativity, its just the opposite actually. But, I think that sometimes you have to think within some kind of known framework and then figure out ways to be creative within that.
This is truly the hard part I believe. You have to know the boundaries of the box and then figure out how to stretch in ways that reach new parts of the box.
Oftentimes, if you want to solve an existing problem, there is a box that you have to consider, lets just be real.
But maybe thinking something is outside of the box is really the fallacy, maybe there is no outside of the box.
