How do you decide when a product is actually "ready" to ship?

I have a bad habit and I am pretty sure a lot of you can relate to this. I am absolutely terrible at launching stuff.

Every time I get close to shipping an MVP my brain starts making excuses. I tell myself it needs push notifications first or the onboarding flow feels a bit clunky or maybe I should just add dark mode before sharing it with anyone.

Before I even realize it two weeks turn into two months. The initial excitement for the project dies down and the code just sits on my hard drive untouched.

Logically I know an MVP is supposed to be basic and simple. But the developer side of me panics at the thought of putting out something that is not completely polished.

For those of you who actually ship regularly how do you kill this perfectionism. What is your rule for deciding an app is good enough to go live even when it feels incomplete to you?
