If you believe that you have difficulty being assertive in certain aspects of your life, discuss what situations present difficulty for you and what thoughts or feelings you have in connection with those times. If you marked yourself high, and don't see significant areas where you need to improve, discuss how your ability to be assertive developed, and (especially if you've discussed your assertiveness and it's development) how you would coach someone who is afraid to assert themselves because they fear being wrong, or that they may upset or alienate another person.
