Watch this. What he has to say about ‘writing what you know’ is spot on.
‘You have to know what it is that is driving you to do this completely narcissistic and asocial act of creating, of forcing your thoughts and feelings upon a world that does not care. And you have to honestly figure out what it is you care about.’
I’m still working this out myself but I’ve written enough now to realise that the process itself, the act of writing is fundamental to reaching an answer. Compiling my short fiction collection and reading my work back to myself taught me much more about what it is I am trying to do with my writing than sitting around thinking about it could ever have done.
Know what you know. Write what you know. What you write will show you what it is you care about.
