As said on the opening page I write short stories. I attend a writing group where we listen to each others stories.
The inspiration for writing comes from many places. Some people write from their own life experience, memories good and bad from childhood, marriage, workdays, friendships. An idea could come from a painting, a work of sculpture or simply a prompt from other members of your writing group if you attend one.
Some people come from a mental health problem. I have a degenerative brain condition. It doesn't matter, creativity comes from anywhere.
I like to draw characters. Layer by layer to slowly reveal him/her. To imagine them in different situations and how they would react to others. I wonder if any of them are extensions of my self and that's quite a scary thought!
Your best stories are usually the ones you have fun writing, but I could be wrong......
