Shortly after the publication of my book,"Just Listen" Discover the Secret to Getting Through to Absolutely Anyone, I gave a presentation to a financial services company that prides themselves on understanding their client's needs because they said they wanted to improve their listening skills.
In such presentations in addition to providing something didactic, I like to facilitate discussion and sharing of best approaches from the participants. I also ask that top performers be forthcoming with the best techniques they have learned.
Two thirds of the way through my presentation I explained a few of the approaches from my book they could use. After I finished making my points, one person pointed out that what I had suggested was exactly an approach that the most successful person in the group used, but never shared with others.
