We are what we believe we are. - C.S.Lewis

As children we pretend to be superheroes, princesses, doctors, policemen and even mothers and fathers and we truly believe that's who we are while we are playing.
However, as adults we struggle in believing that we can accomplish our goals or that we aren't as good as the other guy and that keeps us from taking risks.
Adults need to remember how it was to be a kid, because the way children believe is a lesson that all adults should implement in their lives!
