Some of the best and most famous photographic images ever recorded on film have come from photojournalists. Most of these have been of historical and sometimes tragic events. A good photojournalist has to know how to use the camera equipment and be ready to use it. An important event could pass you by if you're not sure what you are doing. Photojournalists often have to ask themselves if the photos are ethically right. It's a struggle with your conscience when taking photos of a mother who has just lost a child or of a tragic car accident. It's a decision that one must make very quickly, as there is a code of ethics to follow and laws must be respected. Don't be afraid to be aggressive, but always respect your subjects no matter who they are. You must also use your imagination as some assignments won't have a great human interest value, so the less spectacular the subject is, the more important your imagination becomes.
Have as much fun as you can with photojournalism and don't be afraid to take as many photos as needed, especially with a digital camera. You may find yourself with a masterpiece or a historically significant shot. A good photo will often tell a story all by itself. Like everyone says, "A picture is worth a thousand words.
