Write about yourself in the context of your family. Carry out research into the role of the family in society and in shaping its individual members. Some sociologists and psychologists believe that your place in the family affects your character; the eldest child, for instance being brought up with an over-developed sense of responsibility.
Write about class, relating your own experience, for instance, with Marxist theories. Marxism relies heavily on the importance of economic status, believing that most other aspects of life relate back to this. Therefore, according to this perspective, your family's economic status will have profoundly influenced your chances in life. Critics of this perspective would view other issues as equally important. It is possible, for instance, to be born into a family that is low in economic status, but high in aspiration. Relate these viewpoints to your own experience.
Discuss other aspects of your life and experience, in relation to sociological theories. Your area of origin is important, as is your gender and your cultural groups. Research sociological theories about your ethnicity if you feel that this has been an important factor in shaping who you are. Studies have been carried out on, for instance, the effects of being part of a minority group, or being an immigrant.
