This is simple, it only needs hard work and not much of creativity and of course you are a salesman someone needs to guide you in this direction(which I am trying to do).
Two Basic Things That Large Number of Salesmen Do Not Do:
Master Your Product/s or Service/s – Know in and out of what you are going to sell. This is the least expected to do. But somehow you tend to forget this. Also create a database of all the questions a customer asks or can ask you about your product.
Master Your Competitors Product/s or Service/s – Simple take the brochure that they give to their customers, find out online do whatever but you should know your competitors as well as you know your own.
You must do both to get a great results as these are the two things all customers always ask. This might sound simple but will bring about huge change in the lives of those who are not doing it. And those who do it know how important it is.
