I talk about this a lot.
Perfectionism, 100%, is a safe place.
You never get there, you never arrive.
So whatever you were chasing doesn’t ever get tested, get disproven, doesn’t ever have to live and fight and grow.
Back yourself.
80% and launch.
The final 20% either doesn’t matter or you do it after launch, after you see payback.
That final 20% (if needed) will be better for having launch data.
Back yourself.
80% and launch.
