Can they feel my voice?
Connect with your audience or your message and words are irrelevant. Paint with two brushes. One soaked with logic. One with emotion. Your presentation's portrait must have both to fully satisfy your audience's need. They sit with a singular need to be moved by your craft. You could feed only their head. You could feed only their heart. But why would you ever stand up just to settle for only? Be bare. Be complete. Paint with both and feed their spirit. In the moment they feel your voice... they think more clearly about their own.
