A character decides to knock on a door. Your draft then explains the decision, predicts the response and describes the walk down the corridor. The scene might have ended earlier with more energy left for the reader.
Locate the irreversible small change
Find the moment when the character moves from considering to choosing. It need not be dramatic: sending an invitation or setting aside a key can change what happens next. Mark that point before cutting anything.
Test two endings
Keep one version ending at the choice and another including the immediate consequence. Read the beginning of the next scene after each. Which version gives enough orientation without repeating information? The earlier ending is not automatically stronger if it makes the transition confusing.
Save the removed material separately while experimenting. A sentence explaining motivation may belong earlier, where it shapes anticipation, rather than after the choice. This exercise helps you distinguish what the reader needs to understand from what the writer needed to discover while drafting the scene.
