A citizen testifier usually has a minute or two at most to make a concise statement along the following lines:
Most people will do best to have a statement prepared (at least in outline form) and practiced in the mirror at home before going to testify.
At committee meetings at the Minnesota State Capitol, there's usually a table to sit at, with a microphone on it. It's usually best to be within a foot or so of the microphone, so that everyone can hear.
Relax, breath, don't let the idea that everyone is listening to you make you feel that "it's about you"; it's not. It's about what you've felt so passionately, that you've overcome your bashfulness to come to speak it out.
It's every bit as important as they say in the video: you will have an impact!
