Once you have decided what you want to write about, you need to stop and consider if you have chosen a feasible topic that meets the assignment’s purpose.
If you have chosen a very large topic for a research paper assignment, you need to create a feasible focus that’s researchable. For example, you might write about something like the Vietnam War, specifically the economic impact of the war on the U.S. economy.
If you have chosen a topic for a non-research assignment, you still need to narrow the focus of the paper to something manageable that allows you to go in-depth in the writing. For instance, you might have a goal of writing about the nursing profession but with a specific focus on what the daily routine is like for a nurse at your local pediatric hospital.
The important thing is to think about your assignment requirements, including length requirements, and make sure you have found a topic that is specific enough to be engaging and interesting and will fit within the assignment requirements.
