Honestly, I struggle with it, ... I don't think I've ever had a comment on it, but I know my own uming and uhing annoys me. I get so anxious and OCD-y, that I struggle to think, let alone speak. Problem is, I want to kick up a YouTube channel, in which I "present" something, but I don't really want to spend all that time editing out my ums and uhs. ¬_¬
