But we also have to look at our work with a critical eye and say, "Okay, it's not perfect. It needs to be edited. This part needs to be rewritten." Sometimes (and it happens to all of us) we have to admit that the story we've written isn't working, and scrap it or re-write it completely.
The tricky part is striking that balance. Too much in one direction, and we become an egomaniac, thrusting terrible work into the hands of others and refusing to change. Too much in the other direction, and we hoard our work or never complete it, and never become what we all dream of: a published author.
I think the key to striking that balance is impartial criticism. We need beta readers, editors, critique partners, and even friends and family who can read our work and give their honest opinion. It won't always be right - sometimes someone may love our work when it's crap, and someone may hate it when it's brilliant - but it's crucial to breaking out of that insular bubble of our own heads.
