Using Reciprocity to Motivate
One point of influence is the law of reciprocity. This has been proven to be very effective time and time again. Even a movie was made about it. Each time you give something of value, expect other people to give you something in return. This has been proven to be true in a lot of cases. Sometimes, when we give something to others, they unknowingly give back or even feel obliged to reciprocate in one way or another. And it also feels so good. More business is won if comes from a place of servitude.
