Specifically the writing of a technical book, but it has lots and lots and lots in common with writing any kind of non-fic book.

What is it like to write a technical book?

It goes into detail regarding the author’s experience scheduling, outlining, editing, working with reviewers and co-authors, losing track of info that’s in there somewhere, the staggering amount of time that goes into it (no, don’t work out the per-hour breakdown of your flat fee, it will make you weep), and other associated issues.

Among them are these phrases, which resonated with me:

There’s a non-linear relationship between pages and work […]. Do you have a quiet place completely free from interruptions where you can work? Don’t be surprised if you lose 15 or 30 minutes of flow every time you’re interrupted. That seems like a lot, but if you’re keeping a lot of stuff in your mental workspace, and someone calls or pops in to ask if you can help them with something, you might find yourself becoming extremely irritable and impatient — I do anyway — and that feeling itself is as much of a productivity killer as the interruption.
