I love this perspective and agree, however I do think there are some interesting similarities in my job as a software engineer.

If my brain isn't working great, instead of fixing the biggest problem, sometimes I'll do the little, small, easy stuff that needs to get done.

Just like in writing, I show up every day.

But some days I recognize that my efforts may be less than optimal for thinking through a critical large peice of plot architecture. But I can certainly tackle some of the smaller todos and make important headway on the project.
