Yeah, it’s weird to me how many people think ‘oh person [X] has made it at [Y] so clearly they no longer think about [Y] for their own purposes’ when no, if you’ve made it at [Y] you probably think about it even more, just on other levels. Get three comedians on a podcast and they’ll get into details of joke construction, etc.
I think ‘write every day’ is good advice for most people, especially starting out, but that is more about habits and training and getting you to try at all and pushing past that ‘can’t do it’ thing, than about trying to solve a particular piece of writing.
If I ever did try seriously to write fiction I think I would force myself to have word minimums like that, tho.
Great question. The conscious answer is none, but that is a good reason to write more things like this.
