Do you have a passion for your product?
Do you believe in the product you are selling?
Would you personally purchase or use your own product or service?
If you answered NO to any of these questions you are selling the wrong product or service. In order to have true sales integrity you need to believe whole heartedly in the product you are selling. People will say yes more to your belief in your product and your conviction than any other reason. Therefore to attain greatness in your sales efforts and to become truly successful you need to be passionate about your product and believe in what you sell.
