Don Neal of Leading Authorities, on the DC tour stop let me shoot a video of his top three tips for powerful public speaking - go here to see it.
What powers a great speaker?
• PASSION: A deep passion for their message
• ELEVATOR PITCH: Nail the 15-20 seconds of your personal branding “pitch”
• PERSONAL BRAND: Elevator pitch must reflect your personal brand
• STORY: Tell a story to communicate your personal brand
• WANT IT/DESIRE: You have to want to speak in order to get better

Wonderful ideas! Also, I was struck by how comfortable and present he seemed in front of the camera.
Nice. Always got some great advice on your blog :)
