No, the point of this anecdote is that you get good at quality by pursuing quantity.
It's an appealing idea because it's counterintuitive, and here on HN were are absolute suckers for contrarian ways to outsmart the herd. But we have been given no reason to think it actually works.
Well, in writing terms, it seems to have worked for Ray Bradbury:
> The best hygiene for beginning writers or intermediate writers is to write a hell of a lot of short stories. If you can write one short story a week—it doesn’t matter what the quality is to start, but at least you’re practicing, and at the end of the year you have 52 short stories, and I defy you to write 52 bad ones. Can’t be done. At the end of 30 weeks or 40 weeks or at the end of the year, all of a sudden a story will come that’s just wonderful.
... incidentally, also Neil Gaiman's advice in the Masterclass lectures.
The reason it works so well for writing is, as Neil Gaiman points out, that if you work for a year on one story, you've probably practised starting a story 52 times. But you've still only practised finishing a story once. And getting into the habit of finishing things is one of the most important habits to get into.
