When the Pope was visiting America, more than one article commented on the fact that Pope Benedict was not the showman that Pope John Paul was.  It was not to be disrespectful to Pope Benedict and I mean no disrespect by mentioning this, but if the Pope needs showbusiness techniques to sell his message shouldn't you be utilizing the same methods to get your point across?

While Pope John Paul was a showman, Pope Benedict uses a lot of the same methods that successful entertainers use too.

The most obvious is the image.Not only does he have the image of being the Pope but his red Prada shoes help distinguish him from previous pontiffs.  His German heritage also creates a strong image.

Now the Pope's shoes have nothing to do with his message, but I overheard many conversations where people were talking about his footware. 

If people are talking about his shoes, it opens the door for people to talk about the message he is telling.

The same will work for you in the world of sales.  Develop a strong positive image and people will be more willing to hear your message and to be talking about you.
