I feel like I have written a paper before that lacked a narrow focus. The outcome of that paper was that it was all over the place and might have been hard for another reader to follow or understand exactly what the main focus was supposed to be and you just get lost in everything. I do see the importance and value of a specific problem to identify and focus. When you are writing a paper you don’t want to lack a narrow focus because you want your paper to flow right and get the point across that you are trying to make. You don’t want your paper to be so broad that you get lost and forget what the specific focus is.
