That smile you get from joy in the middle of a problem is like the rainbow that comes out after a storm. When you go through a problem, approach a baby, a child and you will see how for a moment you will forget the problems. Because children by their innocence live happy so the world is falling and his smile is the purest there is. Let's live as a happy child despite the circumstance, we do not know if he will see a tomorrow and we do not live happy the present because of the problems.
