The ability to influence a person with words can be very useful in life. Often there are situations when it is necessary to force a person to accept your opinion and change their ideas about any subject. This skill is especially appreciated among diplomats, politicians, intelligence officers and other professions who work directly with people.
First, you need to identify the dominant human perception system. That is, to find out how he receives most of the information: through hearing, sight or tactile sensations. Usually a person indicates this himself, only unconsciously. If he constantly asks you to look at something, then the visual system is dominant. If you hear - auditory.
Then create a comfortable atmosphere of mutual understanding. Listen carefully to the person, note what words they use, where they pause, and so on. You must imitate his manner of speaking. This is not so easy to do, given that the interlocutor should not notice obvious deviations in your behavior. It is even advisable to stand in the same position as he, then the conversation will flow even more comfortably.
After that, you can proceed to the impact. Tell us exactly what you want to get. Depending on the temperament of the other person, your speech can be aggressive, calm, or pleading. Ideal if you manage to confuse the other person. At this point, he will understand little and will almost certainly agree to help you.
