I think knocking off 50,000 words in 30 days is ambitious for anyone who can't devote at least 5 days a week to the process; it averages out to 1667 words a day if you are able to write every day for 30 days straight. As someone who genuinely loves to write but still has to work for a living, I'm pretty sure I couldn't sustain that pace. So my hat is off to those that can pull it off and find the process helpful.
And I will say, one tip for being a productive writer is to avoid distractions as much as possible, especially social media... I've never done it, but there are "writing retreats" available where professional writers and freelancers can gather and go "offline" for a few days. The ones in my area are usually conducted in secluded locations.
As for Grass Planet, I'd still be flattered if, maybe, it got up to 20 reads by the end of the year. I would rather win because people read the story and thought it was good, and not just because they were impressed (intimidated?) by the word count.
