Mind Becoming Mushy

I thoroughly enjoy reading.  In college one summer, I read something like 23 books in 23 days because I could read 6 of the 8 hours I was at work.

This semester, three of my classes have heavily front-loaded their classes with reading.  There has not been a week that I have not been required to read 3 full books and parts of others.  It is starting to drain my mind, as I don't get to choose the book, and quickly must process the book so I can move onto the other.

I would enjoy this process more if I could further ponder each book I read, or if I got to choose the books.  I've noticed my mind becoming mushy the last couple of days.  I'll be looking forward to next week when my "reading weeks" begin and I open up 16 more hours a week without classes to read and process this material.
