People have been mastering the art of selling products and services to those who need them since the beginning of time. The methods that entrepreneurs use to sell their goods have changed down through the millennia, but the principles are still the same.
No sale happens until a buyer is convinced that he will benefit by making the purchase. The buyer has to believe that what he is giving up in exchange is worth less than what he is getting. A person who walks into a fast food restaurant values the meal more than the few dollars that the meal will cost. If the buyer doesn’t perceive that he is getting more than he’s giving, there is no transaction.
