While I like the idea of using small pockets of time for reading a few pages here and there, the practice I find more difficult. I need these few minutes for my brain to stop braining momentarily. I have tried carrying a book with me, but when I did crack it open I typically read a paragraph, reread that paragraph, and then conceded that I don't recall what I just "read".
Likely it's a me problem, but I'm mentally so tired that I simply cannot maintain an uninterrupted stream of tasks even if the interstitial spaces are filled with something I enjoy like reading.
