You don’t have to read in-full everything ever written about your topic. In fact, you probably can’t. Get comfortable reading through things quickly. Learn how to identify key points and arguments without getting bogged down and reading every word.
Now that you’ve got a paper written, take a moment to congratulate yourself. You have done a lot of work to get to this point! And then, get back to work. You still need to edit your paper before it’s ready to turn in. Remember how you weren’t supposed to worry about being perfect? You still don’t need to worry, but it is time to make your paper as perfect as you possibly can.
A prospectus is a formal proposal of a research project developed to convince a reader (a professor or research committee, or later in life, a project coordinator, funding agency, or the like) that the research can be carried out and will yield worthwhile results.
If you want to find helpful and reliable sources of information, the library is literally the best place to look around. There are numerous books, published articles, journals and etc. that you can choose from about your chosen topic.
Creating an outline is really about structuring your paper. Don’t be too formulaic, but it can be helpful to follow patterns and guides.
