As an introverted sales and marketing professional I can speak to the fact that one can make a very successful salesperson.

As an introvert we tend to listen more than speak and this is vital in the sales process. With the proper sales training you will learn to leverage things you learn about people to sale your product.

My recommendation would be to take a sales course. Learn a method. Once you practice and are confident on the process you will do amazing by being introverted.

Give me a call if you would like to learn more. I can even teach you advance selling techniques.

Hope this helps!
