I have to live with my mistakes, but I don’t have to regret them. I regret my actions but I can’t regret the consequences. We all make our own paths in life. Everyone we meet, everything we do, it changes us. It makes us who we are. And, if we’re lucky, we’re given the chance to make things right again.
