Choose a Specific Audience
Thinking of a specific group, and even a specific person to speak to will clarify your message
Think of a personal conversation, rather than a public speech
Remember never to say anything you wouldn't want broadly known
Say the Most Important Thing
The more information you try to communicate the muddier your message will be
Choose only one message to communicate and focus on that message
Make it Personal
Share something you feel passionate about, and let that passion show
If you don't care, no one else will
Outline, Don't Script
Unless your a professional actor, a script will tend to make you sound stiff and awkward
If you have no structure you'll ramble
Use an outline with thought bullets rather than specific phrases/sentences, and then speak naturally and from your heart
Reinforce Your Message
Everything about your video, from the location to the lighting sends a message
Take control and make decisions that reinforce what you're trying to say
Use your location, sound, music, and lighting choices to tell your story, rather than letting them tell their own story that isn't a part of your message
