When we were young we were fearless. You talk to children and ask what they want to be when they grow up and the answers will widely vary. Some may want to be President, some a garbage person, some an astronaut, some a doctor, but rarely will they say they want to do anything average or mundane with their life.
When I was really young and obviously had no clue about reality I wanted to be Superman. I had my trusty pillow case my mom would pin to the back of my shirt and I’m sure I really believed I was Superman running down the street (faster than a speeding bullet I might add). Everything is possible through the eyes of a child. At what point did you stop believing anything is possible?
