Bob Franquiz @ http://bobfranquiz.typepad.com summarized what could be considered as common in the process of preaching. He outlined what is his relationship with every message taught:
Wednesday: I love it, I can't wait to teach it
Thursday: Anticipation building. This is going to be awesome!
Friday: I can't look at it anymore! I hate it. I wouldn't teach this message at gunpoint!
Saturday: It might not be as bad as I originally thought. This might actually be preach-able.
Sunday: I think it went pretty well. I don't know how, but God used it. I wish I would just say what I wrote :)
Monday: I'm never preaching again!
Tuesday: I'm thinking about preaching again :)
