This is an amazing thought to be thinking, if you allow yourself to do so. Try, just for a moment to think of what your childhood might have been like had you not believed in any of those magical wonders. It would not have been the same, would it? Even though as we grow older and seem to forget about what once used to delight and entice us into chasing after make believe, a part of us will always hold on to what made us so happy.
Believe in what you once used to thrive off, for it may heighten and enlighten you. Dragons, fairies and all other myths we were introduced to as small children will forever linger in the backs of our minds for as long as we all shall live. It never truly dies out with age, as is obvious by this Lennon quote.
