No matter what topic you are writing about, you should be able to come up with something in life that helps you relate to the situation. This could be something you experienced yourself, something you witnessed, or something someone else told you about.
For instance, say you are asked to write about a camera. Maybe you haven't used that particular camera and you need to base it off the thoughts and experiences of others. Don't just get the cold, hard facts. Insert situations and experiences as well.
At times, content may not call for first-person writing. However, that doesn't mean you can't indirectly refer to the action. In first person you might write "I laughed hysterically as Susie struggled just figuring out where the flash button was located." Indirectly, you might instead write "Some may struggle amongst the giggles of friends while feverishly looking for the flash button."
Why use personal experiences. Why not just tell readers the facts?
It's simple.
Readers want the facts, but at the same time, they are tired of hearing the same things over and over and over again. I know that rings true for myself. In fact, some fellow writers and I recently had a discussion about this very topic. When you just state the facts, you not only start sounding like every other article out there, but readers may not even move past the first few sentences.
Personal experience keeps the readers interested and it also puts a new perspective on the topic. How many articles out there can you read on "How to Groom Your Dog?" I mean, really, you wash, clip, and dry. But, an article with the title and subject matter of "Groom Your Poodle to Look Like Beyonce" would be a unique perspective. Not that I know how to do this. Obviously, that was an "out-there" suggestion, but you get the point.
Be unique and use personal experience.
Otherwise, your article is just another minnow at the bottom of the ocean.
