This is advice from someone who went from 10 books/year to 52 (1 book/week as described).

I think practical tips for someone already a frequent reader are probably different that for someone who reads 'a bit', a few a year at most. I'd be very happy if I got to 10/year consistently. But that would a) be more than 5.2x-ing; b) be a harder initial curve than the 10 to 52 region, I imagine.
