In agreement, there is a paragraph at: https://en.wikipedia.org/wiki/Skimming_(reading)#Skimming_an...

...that if read (uh, slowly, for that first paragraph or 2 in that section on skimming) has ideas that help me a lot: reading the beginning/end, decide whether to read more, based on life purpose and priorities, and whether I am trying to focus on a task or just relax and enjoy. Also depending on the kind of material and how it is written.

ps: lately I have been thinking I have so many "actionable" ideas and things piled up in my notes, that I try (sometimes?) to read or note only those things that are >=85% likely to change my thoughts or actions for the better in the next 3-4 months; very questionable whether I am good at that. YMMV.
