" One of Eric’s most basic rules is sort of a golden rule for management: Make sure you would work for yourself. If you are so bad as a manager that you as a worker would hate working for you, then you have some work to do. The best tool we have found for this is the self-review: At least once per year, write a review of your own performance, then read it and see if you would work for you. And then, share it with the people who do in fact work for you. This will elicit greater insights than the standard 360-degree review process, because when you are initiating criticism of yourself it gives others the freedom to be more honest. "
