There is NEVER enough free time to read. When I first started grad school, I asked a prof how to get all the reading done (about 1500 pp per week). She responded, “Learn to speed read”. I said “but I DO speed read”. She then said “Learn to speed read....FASTER”.
I speed read, but haven’t measured it (how else can I keep up with things here). But there is a limit to my ‘buffer’ capacity. Trying to get through some CS lewis and you CAN’T speed read that!
