More from Arthur Schopenhauer

• After your death you will be what you were before your birth.
• Everyone takes the limits of his own vision for the limits of the world.
• In early life, as we contemplate our coming life, we are like children in a theater before the curtain is raised, sitting there in high spirits and eagerly wating for the play to begin.
