Pick one thing* that would make you a more powerful presenter and consciously weave that into your everyday conversations until it takes root.

*For example, stronger eye contact, more inflection in your voice, better posture, smiling, animated facial expressions, more arm and hand movements, pausing for effect, listening with your eyes, speaking in a larger voice, building the takeaway into the very opening, storytelling, more use of metaphors and similes, ending with a call to action, pacing. Pick something already.
