["I am starting a job next week in a new school as a teacher and I have to give a speech in front of the entire school. Pubic speaking in front of that many people isn't my favorite thing.", 'I have heard that if you look at one person in the audience and focus on them in their underwear you will relax', "Ha ha.  I have heard that too.  I'm worried that if I think of something too comical that I'll forget what part of the speech I'm in.  I did read something that said to look above everyone just slightly because they think you're looking up at them but you're really looking toward the back of the room. I'm not sure."]
There is many ways to find the relax zone when speaking in front of a group.
