How to read people personality?

Reading people who you know or don't know is tricky ? I will try to explain these two categories in clear steps.knowing people means knowing their personality and habits.once you knew that you know a person because you got to know their personality such as dramatic,worrier,easy going,old school,explorer and stigma fighter. Also once you know their habits such as liar,hypocritic,straight forward to the point,deceiver, hater.you get to know that person however what people know is not what people had told or watched.thats a major mistake since knowing a person comes by observing the person reaction and life sequence. So if you know some one think again how much I can tell regarding that person . So that method will combine knowing the people you know and do not know.and that question will pop up why should I know someone that I already know for long time?the answer will be it depends on knowing their personality and habits that you already know and the person reaction and life sequence that you might know or not and a lot of us don't. So the method that I will explain today is covering those four section personality, habits person reaction, life sequence. Personality is what frame the person action is he acting as he say or not.i explained some examples above .so you focus on a character of the person and whether or not match what the person say. Habits are a demonstration of a personality in a repetitive action and in long term . So if you are an explorer personality you might have a habit of hunting also you might have a habit of being a liar and the reason is that hunting demonstrate being an explorer and being a liar demonstrate an explorer personality for the reason of secrecy not wanting people call you animal killer or for privacy protection you do not want to show location.person reaction which is a comparison between how a person treat you and others also if the person treat you different that what he promise .does that person sentence complete when he talk or he change his words all the time.also is that person give every one a different word.the last is life sequence and that means does his life history and events proof what he say? Does he show love for cats for example as he said and he curse a cat as being funny and kick it to go away as a joke? It only takes self instinct and intelligence to determine who the person is?
