The Stoics did not advise forgetting mistakes, nor did they encourage rehearsing them endlessly. Regret, when indulged, becomes another way of surrendering control, anchoring the mind to what can no longer be altered. The Stoic task is simpler and harder at once, to look directly at what happened, without distortion, and to extract what is useful.

Seneca reminds us, “The wise man is neither raised up by prosperity nor cast down by adversity.” The past year holds both, but neither deserves ownership of your peace. Success can inflate the ego, failure can shrink it, yet both are external events. What belongs to you is how you judged them, how you responded, and whether you learned. A clear-eyed review of the year is not an act of self-criticism but of self-respect.

Regret often arises from confusing outcome with character. You may have chosen well and still failed, or chosen poorly and succeeded. Stoicism asks you to separate the two. Where your judgment was flawed, correct it. Where your effort was sincere but ineffective, accept the result without resentment. The point of reflection is not to punish yourself, but to refine the faculty that chooses.

To end the year without regret is not to declare it good or bad, but finished. What remains unresolved belongs only as instruction. Take from the past what strengthens judgment, release what merely wounds pride, and step into the next year lighter, not because you forgot, but because you understood.
