If you get a really nasty peer review report, ask a friend to do this for you. (You can do it for them next time.) Ask them to translate the report into actions you can take to resubmit it. You don't need to dwell on the tone of the report, which can be humiliating or even aggrandizing in ways that are not productive. All that matters is the list of steps you're going to take to revise it, either for that journal or another.
