I have that need to be perfect, too. One thing I discovered not too long ago though, is if I trust my inner writer, then more things will appear in my work than my conscious mind planned. The work won't be perfect, but it will be a heck more interesting. These days I work towards perfection and do what I can, but I also cede control when it's time. It's harder to tart a work now, but when I've started, the whole process is far less worrying.
