When you slip up, watch yourself and don't fall into this self-pity trap. Notice the emotion that comes to the surface after you slip up. Maybe it's shame; maybe it's thinking, what's wrong with me? I'm so stupid. Not worthy of help. Not good enough. Nothing works. Everything is against me. It's so and so's fault. Okay, just notice what comes up without jumping onto the bandwagon and believing all of it. Instead of just believing everything your mind is telling you, just become the observer.
