The hardest for me is definitely speaking. Your speaking ability can say alot about you. It can show people if you're confident or not, it conveys that you know what you're talking about. Sometimes I stutter and unarrange words when I'm talking fast, so that's a problem. Writing, on the other hand is easy for me. I can review what I wrote, I can edit it what I wrote, but when it comes to speaking, I can't take back anything I said.
