Answer:
when persuading someone or something it requires 3 goals. which are making them feel comfortable with you, gaining their trust is a big part in persuading, also giving them what they want so it seems like a win win.
Explanation:
the hardest goal would most likely be gaining trust, because maybe they have gone through someone else in the future or someone promoting themselves, and did a horrible job at it. which will effect your chances of winning them over, either as an employee, or as a customer. Once you find a way to persuade them, maybe use something like bills, money, kids, family. Things like this will make the customer overthink their stand in life, and you get a promotion, or you get this someone or something to participate in your activity.
