You've heard the carpenter's adage on efficiency: "measure 2x, cut 1x." Similarly, taking a little more time up front to refine your message will save time in the long run and avoid waste.
That often means reducing the message to its essential points -- no more. Easier said than done.
Just look around.
But there's another advantage. A simple, genuine message also carries more weight than you might expect -- often more than a lengthy detailed tract. This is so often true when delivering a solution to a problem.
Measuring, or listening effectively prevents having to restate, explain, qualify, or defend your response -- all of which saps the energy you wanted to deliver with your words. In trying to recover, you lose the chance to engage, motivate, and inspire. Cutting a piece of mahogany too short? Avoidable, wasteful, unnecessary.
Have you ever caught yourself explaining a lengthy solution to someone before realizing that they really don't care about the details? They just want you to fix the problem. They want you to own the problem just as completely as the solution.
Example: It's 5 minutes before the big game airs LIVE and your service is interrupted. Is a lengthy explanation of the cause really that important to your experience as a customer?
"Listening twice" dramatically improves your chances of delivering the right solution with the right amount of detail.
It's interesting that a basic lesson of service should be given by a craftsman covered in sawdust, carefully measuring and re-measuring a cedar shingle before trimming the fit and climbing a ladder to nail it home.
