What makes a good communicator? Is it having an extensive vocabulary (and making sure your audience knows it), sounding like you ate a thesaurus for breakfast or being able to speak to your audience in such a way that they have no need to ask clarifying questions?
Option three, please. In today’s world, people have very little time to listen to a long-winded speech. The key is to convey the target message in as few words as possible in simple, easy to understand language which leaves little to no room for misinterpretation.
If you aren’t able to say what you want in two paragraphs or less (this post is NOT a good example), perhaps you don’t have a solid understanding of your own message. Go back to the drawing board, determine what the key take-home must be and work back so your message isn’t robot-like – your audience is human and so are you!
