Completely agree about carrying a book around with you, whether digital or analog! I read so much pre and post deployment because of SRP, etc. Just as you said, a few pages at a time.  It’s like the Chipper WOD applied to a book!! I ended up getting a work bag about a year after commissioning, and I always tried to have something in there to spend my waiting time productively.  The habit certainly carries over, whether professional reading, getting homework done, or otherwise.
