One way to get through writer's block is to brainstorm around your idea. In other words, look around your room and try to associate the objects that you see with the item you are writing about. I know this may sound silly, but these associations can open new channels for creativity.
Another thing you can do that is very important is to take a break. While taking this break, go outside and look at the world around you. Go to a park or a popular place. While there, try to associate what you see with the topic you are writing about. Try to find relationships between the two.
These exercises are a good way to break through writer's block and gather new ideas. Try them for yourself and see that they can help you move through this obstacle and generate new and exciting content.
