That was actually a good effective speech for an amateur speaker.
The positives are:
1. His movements kept his audience focused on him.
2. He spoke loud and he clearly spoke each word, so his audience HEARD his message.
3. He was passionate about his subject,
4. He followed his written format.
1. He was obviously nervous and jumpy from lack of experience in public speaking.
2. This nervousness also caused him to lose focus of what he planned to say. However, he was aware of this and per point 3 above, he wisely returned to his written format to keep on track. It was a brave and decent effort on his part.
Public Speaking is a hard thing for most people to do. Fear overwhelms them and Self Consciousness makes them lose track of what they were going to say, and then they start 'um'-ing, stuttering, mind goes blank, repeating phrases and/or thoughts over and over, and the embarrassment makes one very anxious to get off the stage rather than reach the audience with a concise message.
When I took Public Speaking class in College. The class started off with over 30 students. After a few classes, the class size dwindled to about 14 students. The majority dropped because they were fear stricken when the teacher informed them they would be called on to regularly to deliver speeches of their choosing before the entire class.
I was quite nervous on my first speech, I chose as my subject how to throw a baseball so it will curve, a subject I knew quite well. And I demonstrated the different grips and motions to be placed on a baseball to get a sinker, screwball, curve ball, split finger drop pitch. It went well and the teacher allowed a question and answers time where fellow students asked question such as how I get the ball to spin so fast, questions on grips, and on delivery. I felt good when it was over because it went well.
It changed my life. I became a real pain in the ass explaining to others why my ideas are true and theirs are not.
Hey, blame it on speech class.
