In today's workforce the skill ranked higher than all others is (drum roll) communication. And 90% of that communication is non-verbal. So where are you going to go when you want to be a better communicator?
You can't do much better than Deborah London. As a coach/consultant for the Speech Improvement Company she has taught in Pennsylvania, China, Korea, Malaysia and Sri Lanka. Here in New England she is a communications professor at Merrimack College. Recently one of her students landed a top job at ESPN.
Professor Debbie elaborated on the two major modes through which we communicate: inductive and deductive. If you insist on a lengthy preamble before getting to your point then you are an inductive communicator (and probably female). If, on the other hand, you prefer to get right to the point then you fall into the deductive camp. Knowing your own personal mode and that of your listener allows you to adapt your speaking style so that you can be more effective.
So, if you are male, you fall into tickets to the Patriots - Chargers game and you want your wife's blessing then start with a really good story. Just don't tell her she looks fat in her new coat.
