[SlowerThanSlow]

In reading non-fiction, I have very different goals than when reading fiction.

Fiction is strictly for entertainment and for the suspension of reality.

Nonfiction has other purposes, including promoting self-development, gathering of general knowledge, satisfying my curiosity, and getting how-to instruction. I read until I find these kinds of purposes are fulfilled and then I usually stop reading. Here are four current examples:

I am reading an Alexander Hamilton biography. I am stalled about half way through, but feel I have a good understanding of his life and personality now, something I didn't have before. Will I resume reading? Probably, soon, because I am getting curious about it again.

I am reading a tome by Hans Kung, a Catholic theologian that I have carted around the world with me for almost four decades, always intending to read it someday. Each sitting I read about three pages, and that gives me a bunch of things to muse on, so I put it down for a few days, only to take it up again.

I am reading a math book that consists of brief descriptions of various rather fun math problems. I read about one problem a week, and work on the problem in my head as I have time and interest. Then I read another one.

I am reading a how-to book on instrument making. I read the section over and over that corresponds to my actual instrument making efforts in my shop.

Ah yes, for the record, 3 of 4 are electronic, and I read them on my phone or tablet.
