Can introvert person become salesman?

Some people might say that sales people are extrovert person or people who loved to meet and talking to another person, always have topic for discussion and love to have people around him. Well for me the statement are reasonable since the basic of sales is to make other people buy and in order to do so we have to meet and talk to him.

So what about introvert person, who try to avoid meeting other people and love to be left alone, can they be salesman too?
Well they can be a salesman, together with the world changing rapidly they can sell product from internet or newspaper without meeting their buyer.
But if they wish to be direct salesman or a sales person who directly sell the product face to face with the costumer, please consider these steps as follow:

1. Smile
First when you arrive in costumer store just smile at them, introduce your self and shake his hand. This warm greeting will give you positive mind set in costumer thought.

2. Less speak more listen
You can’t just tell the costumer about your product directly on early time, you have to pre sell them by talking something else then directed the conversation to the needs of your product. If this steps bother since introvert are not good at talking, we could just ask him question and let the costumer do the talking, ask about the business, their costumer, what product are top sales in the store etc. by doing the talking the costumer will feel that you respect him and begin to treat you as a friend. Keep asking then guide your question to the needs of your product.

3. The Time has come
If we do the second step cleverly, now your costumer is in open to buy mood. Time has come to sell your product.

Sales activity is not only for extrovert even introvert can be a salesman by smiling to the costumer and listen more than talking (God give us 2 ear and 1 mouth though).
