comprehensive exams or the lack thereof

I do not know if this was a good or bad thing but I've moved my Comps. committee around a bit. I'm now asking someone I admire a great deal do write my English Studies question. She's incredibly smart; nothing gets by her. She will push me. I think this is good but I'm also worried   insecure about whether or not I'll rise to the occasion. Part of me thinks this decision will make me better academically, part of me tells that part to shut the fck up. Welcome to my inner monologue.

I need challenges. But there's a challenge and then there's Mt. Everest. This feels somewhere in between. I don't think I've set myself up for failure but I could be trying to convince myself. (It's crowded in my head.)
