There are so many people, that it's impossible to get to know everyone intimately. But, each human expresses some archetypes, which is important because recognising the archetype(s) of people can give us clues for how to behave around them to get what we want, which is usually just a merry time, but this can also be used during times when you want to seal a business deal, attract a partner, etc. Can you think of any more? For example, if you met a store clerk who was an elderly women, you would interact with her differently than if she was a sexy young woman. It would make sense to treat the clerk with respect, like she is your grandmother- she's probably some's grandmother. What archetypes do you represent? Experiment with adjusting your view of other archetypes accordingly. For example, I've become a man in the last few years, and each child seems more to me like a nieces and nephews than ever before, thus I act accordingly around them. This archetype stuff can get very fine-grain, as there are an endless amount of things we could call an archetype. For example, today I met a store clerk who was an elderly man (age) (sex), who was English (nationality), who was reading a book (enjoys reading), who spoke to me about the days after WW2. There are many different 'styles' of people. Many believe that they dislike being the life of the party, and believe that they can't be.
