Communication is a key to finding what can be unlocked by an idea. Learning how to make the key is almost as important as knowing what lock it fits. Once you have opened a mind to the potential of an idea you are much more able to present it in an understandable fashion.
Consider your audience before you begin. They are the mold you use to make your key. It is much easier open the door to understanding when you hold the key to unlock it in your hand. Once they are open to accepting an idea, you can easily lead them down a path of knowledge and understanding as you are now able to present the information in a manner they are willing to understand.
Communication is not the conveying of an idea; it is the action of creating an atmosphere of interest in the idea.
