We all make our livings selling something to someone. Everyone works on commission. All of us are paid both tangibly and intangibly, on the basis of how well we sell ourselves, our ideas, and our products and services to others. It is not a matter of whether you sell or not, it is only a matter of how good you are at it. All sales success is based on these three principles. They are practiced consciously or unconsciously by every top performing sales professional. The regular application of these principles is guaranteed to dramatically improve the performance of any sales person.
