Any personality type can be good at sales.
Different types of sales require different types of sales people. Determining what type of sales you would be best suited for and where your strengths and weaknesses lie can help to ensure your success in sales. The A-type is strong and will desire a challenge with good compensation and the freedom to accomplish goals. You tend to lead not follow. The B-type is the talker, a people person who will demand recognition and attention, as well as a constant changing atmosphere in which to work.
