I will try to find something that will help me to be much better to know more...
I'm going to have to agree with everyone else. A degree in journalism is a waste of time. Jobs in journalism are very difficult to get, even in the West. In Poland, you have to be an ace or have very good connections, or both.
Like someone else said, get a degree in a more useful field. If you want to become a journalist, study sciences (biology, chemistry, physics, engineering and math). If there is a shortage of good writers in any field, it is precisely here. There are precious few good journalists who write about the sciences.
As for other fields, degrees in the following fields are just about as worthless as one in journalism: psychology, sociology, anthropology, political sciences, communications, media, art, music, film, photography, performing arts, architecture, languages (including English), literature, philosophy, theology, economics, finance, banking, business, management, administration, international relations, tourism and recreation, law, criminal justice, history, agriculture, marketing, gender studies, ethnic studies and just about anything that contains the word "studies".
Basically, too many people study humanities and there are not enough jobs for them when they graduate. To have a chance, you have to 1) have natural PROVEN talent and actual DOCUMENTED achievements before you begin university, 2) go to a top school; 3) be an excellent student; 4) have excellent connections; and 5) be a born self-promoter. Otherwise, the chances are higher that you will end up working in some very-low lousy job for the rest of your life.
Study sciences, especially geological engineering, petroleum engineering or biomedical engineering. Otherwise, study the math-heavy version of the field you like, i.e. econometrics instead of economics, financial mathematics instead of finance, etc.
Math is money.
