Some of my author friends are quite prolific when it comes to the number of words they write each day. Some stick to a daily quota and meet that quota no matter what. Others choose a more manageable and polished quota.
I’m quite happy if I can write 300-500 polished words a day. That might not seem very much, but it’s definitely been more manageable for me. Anyone with little kids running around the house knows exactly what I mean.
