View your life with kindsight. Stop beating yourself up about things from the past. Instead of slapping your forehead and asking "What was I thinking?" breathe and ask yourself the kinder question, "What was I learning?"
Sometimes you just need to talk about something, not to get sympathy or help, but just to kill its power by allowing the truth of things to hit the air.
Oftentimes it's the deepest pain which empowers you to grow into your highest self.
Do not waste time thinking about what you could have done differently. Keep your eyes on the road ahead and do it differently now.
