Being said to whom, where and why? What is the message that needs to be conveyed? How much time do you have?
In any conversation, from telling others what you do to convincing others to buy what you are selling, three things need to be given special attention – Context, Content & Quantity.
Context: Make it as relevant to the listener as possible.
Content: Make it as simple as possible.
Quantity: Conveying the content in as little as possible without affecting the context or the message being conveyed adversely.
