Does reading school textbooks count?
I usually read for about 2 hours a day. An hour at lunch, and an hour before bed during the weekday. It used to be only fiction... but now that I'm back to school part-time, most of that time is taken over by reading the school textbooks.
And weekends are always different. Can be anything from 0 to 15 hours, depending on what's planned and what needs to be done.
