When you identify some activity which you feel comfortable, something that give you happiness or just peace, you going to try to do that most of the time; and if people around you begins to see you doing that, then they going to recognize you on that activity.
It is like (for example) whenever I see something related to anime, at once I remember an old friend who was crazy for those things. Or my other friend who liked the poetry and she lived on function of it. Your personal culture begins to be part of your personality, and you going to act according to.
Actually I'm mad for the books, all my friends know that. And when they hear about a new writer or book that they know going to like me, they try to show me it. It feel awesome to know you are doing what you want, and that is not a problem for anybody. Those are your likes, your hobbies, is your business and nobody else's. Criticism of it, by other people is not important, as long as they have no foundation.
Have a personal culture is also like be different for the rest of the people. Something that identify you, and can change the way other people see you.
