Good Things Outnumber The Bad

If life were entirely devoid of hope, joy and justice, all of us would soon lose heart. We keep on going because we know that this is not the case. We are just as encouraged by the ups as we are disappointed by the downs. Indeed, though we generally prefer to avoid keeping a running tally, we are inclined to suspect that the good things outnumber the bad, quite possibly by a considerable margin. On what is your optimism based? Blind faith? Or wise experience? Trust what inspires you the most.
