It is said that the closer the brain is to the sleeping state, the more creative it is. For this reason, many writers keep their notepad by their beds and make sure that the very first thing they do when they open their eyes each morning, is write.
The resultant notes are called “morning pages”. Morning pages might contain what a writer remembers of their dreams or perhaps the writer will simply jot down the very first words that come to mind that day. Some writers say that this exercise helps them ‘slip’ more easily into what writers’ call the “rapture” when a writer feels ideas are pouring into their mind from elsewhere.
Just as the waking moments are a bridge from the sleeping state into sober reality – the hour before you go to bed is often a creative time with the brain slipping into that semi conscious state. Hence there are plenty of writers who write late at night.
And just to show that there are no rules, there are other writers who find their most productive hours are in the middle of the day when all of life’s busyness is in full swing (the Harry Potter author, J.K. Rowling is a good example. She wrote her first book in a busy Edinburgh café).
So, I guess the point is that different times of the day work for different people and it is really of no consequence whether you are a morning, day or night writer. What is important is that you write and that you find your ideal writing time. Experiment. Find what works for you and then set an hour aside each day at that time and write. Likewise, writers have very personal tastes regarding an environment conducive to writing. There are those who like music or TV buzz in the background and those who can only write in silence. Find whatever works for you.
