Depends on what you mean by "completely satisfied". To me, this means I can't find anything else that needs changed, that the story is as good as I can ever make it, and that I've done my best. With this criteria, then, yes, I can be completely satisfied.
On a few occasions, I've been completely, one hundred percent satisfied with a first draft. This hasn't happened often, three or four times in thirty years, but it has happened.
Now I edit, rewrite, and revise each page as I go, and unless I'm one hundred percent sissified with the page I'm writing, I don't move on to the next page.
There always comes a point when changes do not improve something, but merely make it different. Recognizing this point is critical. I can always make changes. Always. I can't always make improvements.
