No, not that song by a famous group, but the title of my latest 'Beginners' piece in the September issue of Writing Magazine.
It's not uncommon for writers to find themselves staring blankly at a sheet of A4 or a monitor screen, desperately trying to get an idea down. It might be a scene, a piece of dialogue, maybe building a character. But creeping in under the wire is a relentless flow of other ideas for the same project (or maybe others if you're lucky), all of which interrupt and deflect the focus.
Result. Nothing. Or at best a few feeble attempts that are likely to convince nobody, least of all yourself.
We've all been there. It's called trying to bite off more than we can chew.
Far better to push back the unbidden invaders and focus on one at a time. At least then you will accomplish something meaningful.
They might not 'fit' at first, because these are still ideas in the raw... and growing as you work on them. But they're the essential parts of your project.
Like bricks in a wall, each one contributes to the overall work. Create each brick, adding them one by one and filling in the 'mortar' between each layer, and soon you're looking at something approaching a wall... or in your case, a complete story.
