Failure contains data
A failed attempt can identify a weak split, a resource shortage, a risky strategy, or a part of the route that only worked in theory. The important question is not whether the run died. It is whether the cause is clear enough to change the next attempt.
“That was bad” is not useful. “I entered the room without the resource this strategy needs” is useful. Specific failures can become practice targets.
Reset with a reason
Resetting early can protect time when the goal is a specific pace. Continuing can be better when the goal is consistency, late-game practice, or simply finishing the route. Neither choice is automatically correct.
A good rule is to decide what the session is training before the first attempt. Otherwise every mistake starts an argument with yourself.
Keep the attempt human
Challenge runs produce strange failures because they impose strange rules. That is part of their appeal. The run can matter without the room becoming miserable, and a mistake can be funny without pretending it was secretly the plan.
Serious attempts, unserious energy. Learn what broke, keep the good clip, and go again.
