Etzioni focuses on a single kind of part-time work, takes a position on how worthwhile it is, and recommends against it. You could write a similar kind of essay. For example, you could take a position for or against students’ participating in other kinds of part-time work or recreation during the high school or college academic year or over the summer—for example, playing on a sports team, volunteering, completing an internship, studying a musical instrument or a foreign language, or taking an elective class. If you work to support yourself and pay for college, you could focus on why the job either strengthens or weakens you as a person, given your life and career goals. Writing for other students, you would either recommend the job or activity to them or discourage them from pursuing it, giving reasons and support for your position.
