Once I had a conversation with a fifteen year old boy in my church. Henry complained that his speech class at school was distressing. I'm all nervous and the kids make fun of me. He was so desperate he accepted my offer to coach him. You can decide intentionally take a different attitude toward speech-making.
Some people get a lot of pleasure out of making a speech.
Well, here's what I want you to do. I want you to image yourself standing up there before the class, enjoying it, making your speech and imagine that the kids in the class are responding to you with a great deal of affirmation, and enjoyment at what you're saying. Then give it the way you imagined and see how the students respond. The other kids liked the speech. What had happened is that by using good stress management, he had turned bad stress into good stress and it was invigorating.
