I Translate - That Is Why Business Needs Me

Startups can't explain what they do because they're addicted to meaningless jargon, which I would argue is because most people really don't understand the art of communication.

Bottom line it is a TWO-way process - and in that process you need to understand who is listening - and ensure that what you are saying is being heard, understood and reacted to.

Anything else - you are in Broadcast mode.
