I think what I find most frustrating is when I don't really know what I'm trying to say. Because sometimes I'll come across an idea and then I realize, okay, what am I really trying to say with this? And that would be a case where I do go back and maybe just take that one idea or one paragraph and try to go through what I do before I write and go through all the ideas and try to find more support or maybe reshape it a little bit. But yeah, that's probably what frustrates me the most is when I kind of know what I'm trying to say, but maybe I don't really know how to say it or I don't know exactly what I'm saying.
