Looking for a Day9 Video about Becoming a Successful streamer

When Day9 was doing StarCraft 2 dailies, he was talking about what he did to become a successful streamer. One thing he mentioned was he would just get into the habit of talking to himself to wall, to better prepare himself for his dailies. Unfortunately, that is the only thing I remember from the video. Does anyone know this daily # or have a link? Any information would be helpful. Thanks!
