Execution is knowing when another adjustment improves quality and when it protects fear.

Every adjustment feels like improvement while you are making it. Some genuinely are, and some are a way of staying in the safe part of the process where nothing can be judged. Learning which is which is most of what separates people who ship from people who refine indefinitely.

Before the next change, say what it will improve and for whom. If you cannot answer clearly, the change is probably serving your nerves rather than the work.
