Place it at the end of an edit, just after the moment the delayed fix is shown, then follow it with a brief reaction clip to close the scene on the finished result rather than on the wait that came before it.

This is a short 2.4-second clip centered on the line 'I should have done this long ago,' presented as a single brief spoken moment. The words carry a plain sense of belated realization, as if the speaker is looking back at time lost before acting. It fits a listener who recognizes that same delay in their own plans, and it lands because the admission is direct and unadorned.
