You pointed out something I forgot to mention, and that is: keep to a deadline, even if you don’t publish each day. For my short story, I set a deadline of one week, because it is, as you say, easy to edit indefinitely.
Committing to a daily writing and publishing routine is an excellent way to practice discipline, which I applaud. It depends, again, on what your goal is, and it sounds like you achieved (or are in the process of achieving) your first goal of conquering fear and building a routine.
Now, on to your next goal, which may or may not benefit from continuing to publish daily.
