There are some things in life, which posses the power to make us happy no matter what else is going on.  They give us hope for the world and ourselves.  We could wander our whole lives not finding it, or it could come early.  All we know is that once we find it, it changes everything and makes all of the difference.  Only when we find what these things are and learn to block out everything else, then we can find how to be happy.
