The reality is this: there is no true need for creativity. Like literature or art, there was never a period in humanity’s history where creativity was key to survival. That continues to be true today.
In fact, creativity makes you think differently, and thus the more creative a person is, the more they tend to stand out. Being different can be difficult. Just as Socrates, or Galileo.
But unlike these literature, art, and other societal luxuries, creativity can be a major advantage for survival. Most of the major developments for humanity, from the wheel to the printing press to modern medicine, were due to creative leaps in thought. While creativity is not necessary for survival, it is monumental, essential even, for growth.
So what are you, a survivor or a grower?
