As a child you spend your time not knowing all the problems of the world, seeing beauty in things by playing make believe in a fantasy world made by your imagination. As an adult you no longer have the ability to truly imagine, knowing that the problems of the world exist all around you. So instead of pretending what you see in front of you is not the real world as a child does, take the real world and try to shape it into the vision of what you see in your fantasy.
