How can you influence?

In his standard work Influence, The Six Secrets of Persuasion, Robert Cialdini, professor at the University of Arizona, distinguishes six laws of influence.They are powerful instruments for influence and direction and help to achieve results with or through others. 

The Law of Reciprocity. I do something for you without supposedly expecting anything in return, but the fact that I do it selflessly makes you feel obliged to do something in return. The Law of Understanding. I asked you to do something and you promised me. The power of the word binds you to me. The Law of Consistency. You have been doing something the same way for a long time, in the same place, and often at the same time. Your system would prefer to continue this unchanged in this way. The Law of Like-Mindedness. You like me, we have something in common, you look like me, you will do more for me than for anyone else. The law of the Authority. I have a title, I wear a uniform, I have certificates and credentials. You will listen, you will follow me, you will respond to what I say. The Law of Scarcity. There is not much of it, the stock is limited. People want a lot of what is little. Sigmund Freud explains it this way: 'People are more afraid of missing something they may lose than gaining something of equal value.'
