It’s Really a Myth
There is no such thing as writer's block although there is a street in Baltimore, Maryland where several well know writers of their era did stay and pen some outstanding works, William Shakespeare being one of them.
When you feel you have the "block" that's when it is time to read other writers. Especially those in whatever genre you are writing. It's like getting a second opinion
My so-called inspiration comes from real events that happen either around me or based on real-life events. That alone is enough to keep feeding me the information to write down and create the next paragraph or chapter.
When you stop to think about it, nothing we write is new but what we write we give a different "spin". Beef it up or tone it down, the idea is bringing something to the table you will be content to write and for readers to read One of the oldest characters written about is Dracula and over two hundred films. The same thing applies to Frankenstein The plot is always the same, but the "spin" is what sets it apart.
Have your main character enthralling, vibrant. At the same time, you also be enthralling and vibrant.
Yet, for all I put here, there will be times when you have to walk away from the page and give your brain a rest. We all need to eat. We all need to sleep. Without both, we wither and fade but eat a decent meal, get a good sleep in, and the next day you are right as rain. Without the two, you become nervous and frustrated. And that's a no -no.
Stay on the path you've chosen for yourself. Have small discission groups with other writer's such as with this challenge to get feedback.
But it boils down to one thing only.
