Let the last season inform the next one without making every surprise a mistake.

Experience is supposed to improve your guesses, not eliminate them. After a hard year, it is tempting to treat every unexpected turn as evidence that you planned badly, when much of what happens was never available to be foreseen. That habit slowly converts learning into self-blame and makes you plan defensively rather than well; some outcomes are information about the world rather than a verdict on your judgment.

When you review a stretch that went wrong, separate the parts you could have known from the parts nobody could. Carry the first into the next attempt and let the second go.
