Just as you are selling to people, you must also remember that you are not only selling and representing a product or service, but you are in effect selling yourself. When beginning a sales relationship, it is important to remember a few key aspects to representing yourself well.

First, be interesting. If potential customers are bored by you, they have less of a chance of being enthralled by any product or service you are representing.
Develop intellect. Of course you are an intelligent person, but can you converse in an intelligent manner? Can you discuss related subjects with thoughtfulness and hold your clients' interest? You are in their territory now, can you speak their language?
Never be arrogant -- never talk up or down to your potential clients. It's rude and will serve only to alienate them. Respect the buyer, and they will respect you.
Along the same lines, develop your empathy levels. If you can relate to your customers' situations authentically, it helps to build rapport.
Rapport is the most important process in influencing others. It is vital if you want to maintain relationships. Without it, you are unlikely to achieve willing agreement to what you want. People who have excellent rapport with others create harmonious relationships based on trust and understanding of mutual needs.
Finally, the greatest compliment a customer can pay you is to describe you as "professional."
Being professional is not one thing, it is three -- It is what you do, what you say and how you present yourself.
