Be very afraid.
Is your writing scaring you? I’m not calling out all horror writers but people looking to push themselves, find the limits of their writing comfort zone, and push through it. It is hard to do this because we are such creatures of self-preservation, but it is typically here/there, in unchartered waters, that we find that something special. As a writer, hell, as a person, I am always looking to stand out, to be different, to look at the world in a different way. What is the point of everyone being the same? If you’re starting to worry that this is some rant from a newly-enraged teenager, then you’ll be happy to know that I’ve been enraged for nearly half a century.
The other primary … primal?… thing that holds us back, makes us hesitate, is that we are also creatures of vanity – who wants to be seen to fail? Well, for a start, as a writer, you can fail a lot in private first, so no one can see you. Eventually though, you’re going to have to step out, stand up, and declare yourself.
This is me, this is what I write, and this is how I write.
