One of the most important qualities of someone being successful as a sales agent is building trust and rapport and the customer knowing that they can trust you, that you're not just going to take advantage of them just to make a buck, that you're there to really help them and to solve a need and not just throw something at them, make money and run off because that's going to hurt you and hurt other people in the field as well too so you always want to do it right by the customer. That's what makes an agent successful in sales.
