Apply to? No need to apply. Get educated, as in, learn to be a bit objective when relating events, learn how news is reported. Learn that "journalism" isn't editorializing about your pet peeve or favourite product/company. If you're running a blog, you're not a journalist by that alone. It's not enough to describe your day, what you wore, what you ate and what you happened to read in the newspaper and reacted to to be a journalist. Getting paid to write your pieces is, for example, one way of separating yourself from the rest and actually be able to call yourself a journalist. Unless you're going for the "a person who keeps a journal" meaning, which in this context would just be odd.
