The next chapter cannot begin while you keep rewriting the ending of the last one.

Some endings never finish because you keep going back to revise them, replaying the last conversation and imagining the version where you said the right thing. That revision feels productive, like you are working toward closure, but it holds the door open. As long as the last chapter is still in progress, nothing new can start.

Give yourself a defined amount of time with the ending rather than an open one, and then let it stand as it happened, imperfect and unedited. If something in the new chapter genuinely needs your attention, put your energy there instead. Closure usually arrives after you move, not before.
