I've edited for my DH, and both my daughters through college and later works/letters/papers/etc. They are all much more "educated" than I am, but I had the better grade school and high school English teachers than they did. Plus I adored creative writing and had an incredibly supportive high school teacher for it who hand-picked me for her class. I was truly blessed.
I also love to read, that helps me as an occasional "wordsmith".
