Right. More and more nowadays with non-fiction, I read a few chapters, realize I've already heard everything the author has to say, and drop it. Life's too short.

It's also very common for non-fiction books to have 20 pages of substance, but be padded out to 200 or more with repetition and filler.

Indeed. Read those 20 pages, say "OK, I got it," and skip the padding.
