Think about some of the applicable groups and teams that you have been a part of in your past, work, school, and other places and events. What are some of the skills and attributes of the individuals that you feel have managed you well? What skills did they have? Do not limit yourself to personality traits. Include things like organization, creativity, etc. Discuss whether these traits are "learnable" or the sort of attributes that you either have or don't have. Have fun with this and be creative!
