Seventy-two views and no responses. Either it's so good that no one can think of anything to change, or it's so bad that no one knows where to start. Hopefully, it's somewhere in the middle. Comments, please?
It's bad. Look: Go find other threads on other people's letters; they'll be in the Job Hunters subforum. Read the letter, read the discussion. Think about the points that are made and why they make sense. Then try again. We might have something to talk about at that point.
