When you speak from your heart your message takes on an urgency that makes it more compelling. That's why it's important to speak about things that you feel strongly about.
How can you be a powerful speaker or writer without emotion?
Without emotion, it's just a bunch of words and concepts.
There is a dramatic difference in a person's presentation when he or she is emotionally plugged into what they're saying.
We've all seen it both in their power and presence while speaking and in the response they get from their audience. It is a tangible difference.
Here is how to do it:
Tell the truth. Be honest with your audience.
Speak from your head with your heart wide open.
Tell them what you think and how you feel about it.
Speak to people like they're your friends, rather than members of an audience.
