Stop polishing intentions and ship something reality can judge.

Intentions can be refined forever and never encounter a single fact. Shipping submits the work to something outside your own judgment, which is uncomfortable and is the only source of correction available. Polishing what has not been released is polishing your idea of it.

Set a date to release something imperfect and hold it. What comes back will tell you more in a week than months of internal improvement, and most of what you were worried about will not come up.
