Gainning Acceptance through good will or deception?

In career, friendship, or social life, intentionally or not one should sell something to other. In any group we are required to provide contribution. If we want to be accepted we should sell something that the group needs. Otherwise we are no longer a member. Although most people reluctantly admit it selling is what people actually do. We sell our expertise in order to get pay checks. We sell ideas to friends or community in order to get accepted. In any field of expertise or social environment we choose, we sell. John Cantwell Kiley once said that successful salespersons are those who sell their products by expertly calling attention to the blossom instead of hiding the thorns through deception. As a matter of fact this applies in our social life as well. If you want to succeed in selling an idea to friends, first you have to understand the blossom of your idea. You have to know “what’s in it for them”. Then comes the harder part that is how to sell it. You can use an an honest approach or the opposite. When a person hides the thorns (weakness) of his or her idea through deception then we do not appreciate him or her as a good salesperson. Once such truth revealed this person has been put in a black-list and even sent away as an outcast. On the contrary, when a person sell honestly other will acknowledge it as a good reputation.
As Kiley put it, successful salespersons know how to make themselves blossom in the mind of a potential customer despite the thorns (any personal limitations). But he insisted that it should start from the creation of good will (keeping your word to a customer). Doing otherwise is an act of disrespect and contempt for the customer and quickly destroy your most precious asset in selling.
