Fear of not being good enough.
Fear of never being published.
Or if we're published, then fear of not being read.
Or if our stories are read, then they're not read enough to warrant another book sale. Ever.
Fear of never having another idea for a story ...
There is no end to the dread, anxieties, fears and worries that assail us every day. It's a wonder - dare I say, "a miracle?" - that any of us have the wherewithal to write at all. Except that THAT is precisely the only possible response in our arsenal - to trust, believe and own that, "Everything we want is on the other side of fear." Fear is our Looking Glass, our portal, our gateway ... we have to go through it to reach what we want.
Although, as writers, we will never be "Fear Free," I wish you fear-less writing.
Here's a link to Elizabeth Gilbert's most recent post about fear.
For most writers, running out of a coffee is also a soul sucking dread.
