As we try to occupy ourselves in isolation, has it been productive for your writing or not?
There is an emotional component to this particular imposed isolation that is subduing creativity. Our emotions have always influenced our mood and in turn our writing. Strong emotions, such as anger or depression subdue our creativity while feelings of love and happiness enhance it. Our concentration is in short supply or our focus limited. To pour out these feelings in words can dispel some of them.
You may find it is helpful to journal at this time to help lessen your heightened state of anxiety. It is also a record of our experience for future generations but maybe, also, the genus of an idea for a future work/narrative/story.
As writers we use many influences, experiences, emotions and personal knowledge in our narratives and this extreme situation may give us remarkable ideas. Think positively and use it for inspiration.
I think this particular writing tip is also relevant. With some sort of goal or deadline, even if it is only 20 minute sprints in writing can help us.
Set your writing goals for every writing session
Outline your aims for a writing session in order to keep yourself focused. It may help to write down what you want to achieve in the next chapter or scene. However, remember, to give yourself elbow room. It is okay to depart from your scene summary if you feel the story should go (or wants to go) in a new direction. Personally, I let the story flow but some writers find writing a pre-scene enables them to maintain a clear sense of direction for each scene in relation to their story arc.
Maybe hook up with another writer and set a time to write virtually. Find a writing prompt and time yourself. There are ways to encourage your Muse, find the one that works for you.
Take care & stay safe. Stay well.
