I want to be a journalist, but instead a work as a sales Representative at Sears.
Well you have to start somewhere. You have to be educated to report facts, ideas, interaction of events in the daily news.
Not yet,not formally, but I hope to be someday.  I wonder what kind of journalist should I try to become?
Journalism
Journalism is the production and distribution of reports on recent events. The word journalism applies to the occupation, as well as citizen journalists using methods of gathering information and using literary techniques. Journalistic media include print, television, radio, Internet, and, in the past, newsreels.
Concepts of the appropriate role for journalism vary between countries. In some nations, the news media are controlled by government intervention and are not fully independent. In others, the news media are independent of the government but instead operate
issues, with constructive journalism the journalist also addresses what the consumer can do with the information. What can I do to change it? etc. 
The journalist does not reflect his or her opinion and also does not render or implement what those solutions are, but tries to inform the society of what solutions there might be. Pioneers of constructive journalism say that as a journalist you have a big impact on the way people think, because of the way you construct the news. Journalists need to be aware of that responsibility
