Well, I've been retired for 20 years, which makes it easier, but really, I've always read that much. My fixation on books and reading led to a long career in a very large public library system -- but you'd be surprised how much time busy librarians DON'T have to read.

I keep up with a number of series, too, mostly via a directory of checklist text files where I can keep track of whee I am with each one and what's about to be published next. When you read this much, you have to be organized about it, or you miss things.
