Everybody has competition--competition for sales and competition for time.
When you call someone or make a sales presentation, you are competing against hundreds of other things that are trying to get the attention of that person, things that may look or feel more important than your call, right now.
So how do you get a customer to decide to "buy" from you or even just listen to you? You need an unfair advantage--a reason that makes you more attractive to the customer than your competition. You need an advantage that allows you to "speak" in a more persuasive way. That advantage will not be your engineering excellence, your service quality, or your prices. You have only one advantage YOU! The only real "unfair advantage" you can have is a better way to sell YOU, because the customer will always buy you before he/she buys your product. You must shine brighter and more powerfully than your competition, or no one will hear what you have to say.
NLP skills are valuable for influencing anyone anywhere. Whether through mail, on the phone, face-to-face, or in a group presentation, NLP skills get results. You can get a person to listen to you. You can leave voice mail messages that get a response. You can get more information from a secretary or gatekeeper, and you can help people remember and feel good about your company even though you are making only a survey call for information. Any time or place you want to be persuasive, there are several NLP skills that are available to you.
