If you wanna be a fiction writer, you gotta do the work. It doesn't really matter where you work, like from a gorgeous spot out in the Montana wilderness, but you gotta dedicate the time and the headspace. You'll need uninterrupted stretches to:
--Think about your story, AKA plotting
--Write, write, write
--Re-read and check your inner critic. Revisions come after the draft. (Are you editing while you're drafting? Ahhh, I see, you're one of those.)
--Capture thoughts about changes (I do this in a spiral notebook.)
--Think some more, AKA plotting
--Wonder what the hell you're doing
--Resist, resist, resist major editing (Unless you're one of those.)
--Finish a draft
A draft is the newborn phase of your story's life. You don't have anything without a draft – a complete draft with a beginning, middle, and end.
All the other stuff, pacing, voice, character development, world building, proper spelling/grammar, dreams of fame, those can be tackled in the editing phase. Don't get me wrong, editing is essential. But getting the draft down comes first. Everything else can be fixed.
Whatcha waiting for?
