Getting started in narratives is often the hardest part. Once a story is begun, it is a lot easier to continue and finish it.
Here in Australia, narratives and stories are required to be taught from a very young age. It is covered as early as kindergarten focusing on one single event and with every year beyond that, it increases in difficulty and complexity in terms of the way it is written and assessed. It is a key component in the NAPLAN test, Selective and all throughout high school including the HSC exam in year 12. There are many components of a narrative but they all will require an introduction.
