Their is one trait that is often undervalued. It keeps the mind open to new ways of thinking, new perspectives, exploration of our abilities, and defines our ability to cope with and manage change.
It is curiosity.
When we are curious about anything we seek ways to satisfy it. It is self-motivated and stops only we are satisfied with what we find. It is not tied to practicality and actually may be of no use other than we wanted to know.
Curiosity is the mother of innovation as we place with pieces of the puzzle just to see if we can discover new ways to put it together. Curiosity doesn't require justification for it's use. It is creativity in action in a way that is fun and delights us.
It answers the question of why with one of why not. It can be a poke in the eye of conformity and flies in the face of normalcy. A good place to be sometimes and can be the founding stones of dreams.
An exercise in imagination and thinking outside the box.
