I believe humans have an innate need to be creative - God is The Creator and we are made in His image.
I don't believe the human need to be creative is all about "art" or ethereal expression - it's just about engaging our brains.
I believe that in today's world, we lack opportunities to be "creative" because we have machines, computers, factories and stores to do and provide so many things for us. We don't have to problem solve or find alternatives, research, learn by trial and error, or build and create things. How often do we get to use our imagination?
I believe if we live life without tapping this part of our mind, we constantly feel unfulfilled, even sad. We lose our human spark. We become bored and boring. We become dull.
