I believe the most important qualities of a successful sales representative is communication, being able to overcome objections, and knowing how to navigate the needs of your client. So being able to show the client different avenues and coming to the best conclusion of what is the best fit for them would require the communication, overcoming the objections, and again, just being able to navigate and knowing the insight of how people think so that, again, you can bring them the best qualities of products to fit their needs.
