New Wounds vs. Old Wounds

"What's worse? New wounds, which are so horribly painful, or old wounds that should have healed years ago and never did? Maybe our old wounds teach us something. They remind us of where we've been and what we've overcome. They teach us lessons that we should avoid in the future. That, we like to think. But that's not the way is it? Some things we just have to learn over, and over again."
