This. I had a teacher once tell us that the only way to get better at reading was to just keep on reading. Sure the beginning, you'll probably be trash, much like anything, however after you get the hang of it, you'll be able to read as much as 300 pages per day, maybe even more. However, much like everything else, you have to continue reading even after you've reached your goal, or else you fall back into not being able to read as much. This happened to me, when I was a kid, I'd be able to read so much in a day, because I would just read and read. However, as I got older, I would read less and thus not read as much as I could when I was younger. I've been reading more though, and slowly am able to get to the same skill as I did when I was younger.
