Waiting for perfection is like waiting for Godot. Spoiler: Godot never arrives.
It’s precisely those that want to achieve perfection that will never be satisfied to see perfection when it’s right in front of them.
Is what you have better than it was before? Does it accomplish the main goal? Then start using it.
Could it be better than what it is today? Start using it anyway. Make incremental improvements post-launch.
Ship, learn, iterate, repeat.
