People ask me this question all the time. But it's the wrong question. It indicates very linear thinking about direct response marketing which is, in fact, just not based in reality.
Seems like your leads are not converting into sales? When you start in business, or even just in a sales position, you concept of TIME needs to adjust. Most of you will find that your "trading time for dollars" brain-washing takes over and you start to feel like, "Man, I should be getting paid because I put in some time for 3 days in a row working..." completely missing the point of being in business.
