See through their souls And the things they like, Write like they want to read it. The writing style that according to them Shall be successful. Make it more simple, More complex, Whatever they like, Make it realistic, Or dreamy, Happy Or sad. Tell a story They would tell themselves.
I go to this writing contest every year since 5th grade, i got the 2nd place 3 times and 1st place once. The only time i didn't get anything was in 6th grade, when i wrote how i liked it. Trust me, on those you won't get far, you have to write how they like it. But it's also very important to write how YOU like it, otherwise it becomes another task.
