How do you know if you are manipulating somebody?

Both influence and manipulation involve getting somebody to do what you say. The difference is that if the person knew what you know, would they still make the same decision? If they had all the information, would they still follow your advice?

How would they feel after making the decision? Would they be glad they listened to you? Or would they feel cheated, used or betrayed?

Trust comes with responsibility – the responsibility to not manipulate.
