I am always amused when clients define themselves, food or an entire day by the terms "good" or "bad". This judgement is usually determined by their actions, or an event that has occurred. I typically remark that both adjectives seem a bit extreme. People, food and a twenty four hour period are neither good nor bad. They just are.
We are the ones judging it. There is certainly value in observing something. If I determine that a certain behavior or food item may be harmful to me, I may consider eliminating it.
Rather than waste time replaying and criticizing, it may be more helpful to decide what to do about it.
