Keep up with current affairs. I don’t mean which movie star is getting divorced, but which political policy is getting implemented, where has a coup just taken place, which soccer club was relegated for match-fixing. Start practising writing as often as possible. It doesn’t matter what you write, as long as you keep writing. You will get used to it, so that you relax and your writing improves.

You can do journalism at honours level at many universities. This helps, but what gets you a job is your portfolio. So, submit things to the student newspaper, or get a slot on the student radio station.
