It seems wasteful whenever I hit delete or backspace to rewrite something I have already written. I I hate throwing my words in the trash.
Last night I related this little quirk to a friend of mine who happens to be an English teacher. She knew just what to say to help me in this situation. "You make corrections in math all the time. You don't consider this wasting. By rewriting, you are just correcting like you do in math."
It's funny, I never thought of writing that way. She made so much sense. I rewrote half the lines of this post many times and I am okay with it.
It's great having smart friends.
