Wow! I had a moment of clarity today. I wondered why all my characters look and sound the same - female, male, young, old. I realise that I have a certain personality style (logical, structured planned etc) and so I am portraying the same persona onto all my characters. I guess great writers are able to 'step out of their skin' and allow their characters to take on different personality types. How do other writer's in the community manage to stop their personalities and preferences from seeping into their characters?
