In grammar and writing, there is always something that someone struggles with. Personally, my most common mistake is not rereading my paper. I always end up convincing myself that since I was the one writing I already know what is on the paper so why reread it. Confession: I typically have someone else do if for me because I can’t get myself to do it. Although, I know my papers need rereading and editing it’s always hard to make myself sit down and do it.
