Affiliate Marketing Secrets

Hello, I am a 16 year old and am also well affiliated with my schools Student Council. Matter of fact, I am a high ranked officer, but my speech tells a different story. When we have meeting, we will have some small arguments over certain topics, Its just that, when I’m refuting someone else’s claims, I can’t seem to produce the right amount of speech. I mean I stutter, forget words, and don’t use my extended vocab. I kind of get nervous and I want to get over that. I’m going for President next year and if I win, I want to be able to speak with power and kindness. I’m a good speaker but I really don’t know what happens. Is there anything I can do?
Thanks! 🙂
