Technically well-written, but it lacks substance. I think that you've confused quotations with facts.

A persuasive speech should convince someone to thinking something. But I think I'm just convinced that you can do this! Some people might be motivated to to help, but they might not know what to do even though you said how to do it. While saying the speech you should grab the audience's attention by relating to them, use more "you" instead of "I" Persuade them, not yourself.
