I've also stopped believing that writer's block is a thing. Yes, you can feel less motivated or creative some days, but that shouldn't stop you from writing something, anything, down onto the page. Even if you're just writing about how you can't think of anything to write about, it's better than nothing. There's an article and a quote that I turn to to get rid of the idea that you have to be "in the mood" to write:
Philip Athans' article, "Save the Bullshit Excuses"
And this quote from Stephen's King's On Writing:
I also heard a brilliant comparison on a writing podcast recently. It goes something like this...
Firefighters don't get firefighter's block. They can't show up to work, stand in front of a burning building and say, "Nah, I just don't feel like it today. I just don't think I can do it. I'm not inspired enough."
The sooner you start treating your writing like a job, the more successful you'll be at it. Provided that's what you want it to be one day, you just have to show up and do the work.
By the way, how many resident creative writing challenge writers are planning on making this a side hustle or a career one day, or are maybe already doing it?
Eh, this has always struck me as a pedantic argument more concerned with sounding clever than being accurate, but maybe I'm in the minority on it. "Writer's block" has always to my understanding been "I don't know what to write next for this piece," not "I'm not feeling creative" or "I can't write anything at all." There's a difference between being stuck and not feeling motivated.
My problem is that I don't have a whole lot in my repertoire I feel is worthy of submission. Plus, almost all of my stuff is between 2 and 2.5K words, so that's already an uphill fight to get published.
