Travelling overseas and meeting new people increase one’s knowledge, Derek Sivers said. He added, that those how live in the opposite side of the world have some different understanding. For example, in the USA, one should ask about the streets’ names or numbers; to reach a specific location. To get the right direction in Japan it is important to know the blocks’ numbers; because the streets do not have names. Another strange paradigm has been happening in China, where some doctors charge people while they are healthy, but they do not pay money when they get ill, because those doctors believe that their duty to keep people healthy. Yes I agree that Knowing each other helps to understand cultural differences. Some people think that there is just one way to do something, but communicating with others shows that each part of the world may have its own way of doing things.
