If your gut keeps poking at one part, it’s poking for a reason. Trust the poke.

Persistent unease about a specific section is usually your judgment running ahead of your vocabulary. You cannot yet say what is wrong, so the feeling keeps returning to the same spot, waiting for you to catch up. Ignoring it does not make it go away; it just means the flaw ships.

Go to the part that keeps bothering you and try three different versions of it, even if you like none of them. Often the second attempt reveals what the problem was. If nothing helps, show that section alone to someone and ask what they notice.
