Yes, procrastination until the pressure of an impossible deadline looms can help get over te perfectionist bump. It works for a whole as a "coping" strategy but is extremely toxic in the long run.

I have little help for you. It is a problem I still struggle with. The other option is to stop caring about any goal. I don't recommend it either...

And I have spawned another task avoidant perfectionist frown although fortunately he doesn't seem to have tied his self value into the mess. Not yet anyway.
