To be a great salesperson you have to first sell yourself. What I mean by that is you have to know that you are a great salesperson, that you have the confidence to close a sale regardless of the obstacles if in fact what you are selling is right for your prospect. Once you have learned the skills to be a professional salesperson, there are three ways to gain the self-confidence and be a highly successful salesperson:
Look Like a Professional: How you dress will create an immediate impression on your prospect. If you look professional, you will be perceived as a professional.
Act Like a Professional: How you carry yourself, how you shake the buyers hand, your facial expression all either reinforce of contradict the way you look.
