Just sharing a bit of amusing advice from the rockstar author himself, Neil Gaiman (American Gods, Coraline).
Of all the questions I see from aspiring writers, asking how to get started is probably the most common. And there really is only one answer: just write.
This sort of question always reminds me of the irresistible simplicity of this quote from Bukowski’s Factotum.
‘You think you’re a writer?’
‘… I’m still writing.’
