I'd like to strongly recommend the act of looking at the sheer, horrible, soul-crushing amount of failure in your life.
Really, go ahead, take a look. See it. Feel it. Smell it. Look at all the things you've done wrong. Really, really look at the horrible amount of things you've been a total screw-up at. None of it is going away. None of it can be undone. None of it is leaving. It's all etched in history?
All done? Good. Now get back to leading your life.
