The first two tactics are straightforward and simple — further explanation is not necessary. It is this third technique, the new vantage point, that is interesting. Is it a Jedi mind trick on myself? Am I psychologically deluding myself? I do not know.
But I do know that extreme self-consciousness is unpleasant. And it is even more unpleasant when there are 30 or 40 pairs of eyes looking at you. I found envisioning the scene from a different angle was beneficial in terms of relaxation and self-consciousness. Instead of being at the lectern in the front of the class, I tried to see the action, i.e., my speech, from a completely different place in the room: It could have been 20 feet above me. It could have been 15 feet to my left. It could have been the back of the room.
Wherever it was, however, from this different angle, it was, to a degree, like watching someone else talk. It changed things. I took my center of consciousness out of my body and put it somewhere else in the room. This may sound weird and hokey-pokey. It may seem like a crazy, out-of-body experience. However, it worked. The focus went from extremely internal to less internal; in a way, it went from internal to external. Imagining that I was watching myself from another spot in the room lessened my self-consciousness. It was similar to seeing not myself, but someone else, give the speech.
That alters the framing; the paradigm is shifted. Instead of seeing from the normal place, the eyes and brain inside my skull, I was “seeing” the action as another person in the room. I thought of it as watching a short film. And I was just a character in the film, a character who was giving a speech or presentation at the time, but just a character nonetheless. The paralyzing self-consciousness decreased when I did this.
