Retrospection and Chain of Thought

Lately, I’ve been pondering one question: Is retrospection really worth the time? Many people only reflect after a failure, and even then, they do it reluctantly. But gradually, I’ve come to realize that whether in success or failure, retrospection is essentially building a chain of thought for yourself. Simply put, it’s not just about looking back at the past—it’s about organizing logic, clarifying cause and effect, and making your next move more deliberate.

Retrospection matters because our decisions and actions always unfold in complex environments. With rapid changes and fragmented information, relying solely on intuition and experience often leads to repeated mistakes or missed opportunities. If you can straighten out every decision and every action node, you can connect scattered experiences into a clear logical chain, gradually learning to find a path through complexity. This is not just an accumulation of skills, but also a training of the mind.

Recently, I’ve noticed many people experimenting with large models to assist in retrospection, which I find quite intriguing. For instance, when drafting a proposal, analyzing data, or designing a process, you can simulate different scenarios and predict possible outcomes through the model, allowing you to see the potential impact of your decisions more intuitively. This essentially turns retrospection from a mere review into a “rehearsal,” making the chain of thought more complete. As Lei Jun once said, successful experiences also need to be summarized, or they will fade away with time. By combining retrospection with the chain of thought, both successful and failed cases can serve as references for future actions.

In practice, I’ve gradually developed my own method: first, outline the full picture of the event, noting each key decision and its rationale; then, analyze the results and impacts, mapping out the key causal relationships; finally, consider what alternatives and optimizations exist if a similar situation arises again. Each retrospection generates a chain of thought in my mind, making experiences tangible and actionable. Over time, when faced with new problems, you no longer rely entirely on intuition but have a logical framework to follow, bringing a sense of composure and initiative.

Slowly, I’ve come to realize that retrospection is not just a tool for reviewing the past, but a way to have a dialogue with yourself. It turns fragmented experiences into a coherent chain, making every action traceable and every attempt an accumulation of energy for the future. Retrospection and the chain of thought are like drawing a “mental map” for yourself in a complex environment, allowing you to find direction, feel a sense of control, and embrace freedom even when facing uncertainty.
