how to be a writer by traveling the whole urban in the world

My dream is to become an urban sociologist who can connect the culture meaning with the life mind for everyone.
Although I don't visit any urban in the world, I still get the power to feel the meaning of the urban in the whole world from TV progam such as travelandliving's Samantha Brown (珊曼莎布朗) with 《Passport to Europe with Samantha》(暢遊歐洲),Anthony Bourdain(安東尼波登)(波登不設限), David Rocco (大衛洛可) with the 《David Rocco's Dodce Vita》(甜蜜義大利),Jamie Oliver(傑米奧利佛) (原味主廚).
With their action to visit the different urban, from the restaruants, the hotels, the architectures, the local people and the culture etc., I decide to become an urban sociologist with the culture study and the environment economic. And I am learning France, Japanese, Advance English now for communicate to people. (I just hope I can have more time to learn more language such as Germany, Ilitay, Spanese, Russia etc.)
How can I write articles for making a living and travel at the same time?
I am preparing the test of interpretation or the guide of travel, and I just hope I can meett nice people who really want to enjoy the culture travel in the whole world when I travel with them.
Although I can't become a real urban sociologist by this way, I still can read more life books from the urban by working this way and collect my view of urban to plan the real life for people being a better life.
This will be my whole dream to my life.
Like Anderson Cooper, I can let the story with their real way in my words.
