I have started a blog, to help shape my ideas. Despite having a doctorate, I have been told by one of my former bosses that I wrote poorly. I think he was taking out some frustration: a month before I wrote an incredible piece, published in an awesome journal, and I mentioned people of his ethnic group being treated differently than mine. I also did not like his editing of my personal statement, in ways that minimized the harms done to me by other people.
At any case, I try to pen down an extra 500 words a week about my experiences. Also, I remember even the Pulitzer/Nobel Prize winner Toni Morrison loving the editors pen marks.
Everyone takes edits and marks, everyone needs correction. I think it is frustrating to take edits from a person perceived lesser than you, but they are likely pointing out something extremely important that you are not seeing.
