People have many preferences and some people have different preferences. If one man chooses another man may choose not to be that thing. But there are some things that everyone likes. And those things reveal how tasteful that person is.
Imagine you are walking through a slum area where some people are going about their lifestyle as if that is their taste. But you are a polite and nice society person you can never go there and maintain your live. So you have to adapt to the environment where there are many dynamic people and that society is suitable for you.
Another way to express taste is the way you stay tidy and clean. A hard working man and a country man have many similarities. Keeping your house clean indicates a tasteful person. You wake up in the morning and clean your room as well as make your bed. Thus you will fall into the queue of a brilliant person.
