Here's the lesson of Martin Bayne's item, for those of you who just care about things like sales and technology.

Knowledge is power. If you really want to sell something, immerse yourself in it, and immerse yourself in your customer. Become your customer, insofar as you can. Go native.

You don't have to have Parkinson's or live in a facility to do that. You just have to reach out, to care, to empathize, and try to help.

Here's a good movie which teaches the lesson.

The lead character, Bill Porter, has cerebral palsy, but this is not a movie about a handicap. It's a movie about selling, about caring, about how you, as a salesman, can really make a difference in other peoples' lives. Porter made a difference selling cheap household products door-to-door. Imagine the difference you can make selling something really worthwhile.

And you can. Now take it away, Mr. Bayne.
