Why do we need purpose? The German philosopher, Friedrich Nietzsche, wrote this in his book, The Gay Science:
“Gradually, man has become a fantastic animal that has to fulfill one more condition of existence than any other animal: man has to believe, to know, from time to time why he exists; his race cannot flourish without a periodic trust in life–without faith in reason in life.”
When I read this for the first time, I finally understood why we need purpose.
