Your thesis should express the main idea of your paper without listing all of your reasons or outline your entire paper. It should be a simple statement, rather than a list of support; that’s what the rest of your paper is for!
With a topic selected, the next step is to begin research. Research comes in numerous forms including web pages, journal articles, books, encyclopedias, interviews, and blog posts, among others. Take time to look for professional resources who offer valid research and insight into your topic. Try to use a minimum of five sources to vary your information; never rely on only 1-2 sources.
If you are struggling to come up with a topic that feels “just right,” ask your professor or coworkers/classmates for advice. They will likely have great ideas that, even if they aren’t options for you to choose, can inspire you with new ideas. Asking a professor for help may seem frightening, but if they are worth anything as a professor, they want you to be successful with your work, and will do what they can to make that happen.
Whenever possible, choose a topic that you feel passionate about. Writing about something you enjoy certainly shows in the final product, making it more likely that you will be successful writing a paper about something you enjoy.
