I also think people write about what they like not just what they read. If you write about what you like it will always be true, but with your own little spin on things. To make any story your own you have to to put a spin on it. For example I like to play football and I have played since I was six years old. If I was to write a paper about football I would talk about all the great times I had on the field. I would not just talk about the rules of football.
Another bonus for writing about what you like is you will have more to say in your paper. People will not just be rambling on about something they have no clue about. People who write about what they like and what they know can always make a story unique in their own little way.In Stephen Kings book On Writing he says"Write about what you like, then imbue it with life and make it unique by blending in your own personal knowledge of life, friendship, relationships, and work" (King 161). Always remember to be unique and put your own little twist in what you write. No matter what you write about always feel confident about it.
