Ship in three steps.
Draft, review, release.
Draft
Get a rough version in front of yourself fast. Perfect is later.
Review
A second pair of eyes catches what you have stopped seeing.
Release
Ship it, then watch how it behaves in the wild.
Reviewing is where quality happens.
Review
Read it as if you did not write it. Ask what would confuse a newcomer, and what you are quietly hoping no one notices.
