Don't confuse the two.
Today I read an article published on the web version of CRM Magazine about how people sometimes confuse the difference between selling and marketing. While this article is aimed at CEO's, I think that it is a valuable read for those of you in a sales position as well.
"When CEOs make sales calls that sound like investor presentations, are they selling or marketing? A meeting with a potential customer is a great opportunity for a potential customer to reach the conclusion that you understand their company's situation and needs-or not. If you are "telling your story" to prospective customers instead of asking about their business, how will they ever find out?"
I recommend reading the article, "Don't Confuse Marketing with Selling".
