What sets me apart from other job applicants in marketing?

I believe experience sets me apart from others in the sales and marketing field. I started working in sales at age 16 as a sales associate at Maurices. In this clothing store I learned to read customers to find out what they wanted. My sales climbed steadily until I had the highest in the store. I am currently a marketing intern, where I get to work first hand on advertisements and promotions and learn how we market our commercial spaces to potential clients.
