One thing that makes writing easier: remembering that one story, one piece of flash fiction, one blog post, just isn’t that important. Knowing that no one piece of writing is going to make or break you. Not by itself. It’s the accumulation of them and the culmination.
If you’ve put together a thousand words five hundred times, the five hundred and first is bound to be better than the first hundred. That’s even more true if you’ve written them all in close succession. Given that, my advice to any would be writer would be to write constantly.
Write freely. Haphazardly. And do it constantly.
