A good salesperson
In Spanish there is an expression to refer somebody who can sell everything; "If rock sells, rocks people buy." I do not know if that expression makes sense in English but I think it is the appropriate saying that would fit Steve. He has the energy and the passion that a salesman needs. I also think that the tips he gets from Carmine Gallo helps him to say what people like to hear. One of the tips that we can see is that his presentations are direct and short. So his enthusiasm combined with Carmine's advice makes him very successful in his business.
In some way it is possible to compare a salesperson speech to a paper or article. If the article is well written many people is going to read it. If a product is well presented a lot people is going to buy it.
