If you lose people when you talk, it's because you're not engaging enough.
The 3 areas you need to think about to be engaging are:
1. Auditory engagement - how you sound
2. Visual engagement - how you use body language and hand gestures
3. Content - is what you're saying interesting to the person?
Practice improving these 3 areas if you want to keep people engaged when you speak. It's that simple!
Do YOU struggle with keeping people engaged?
