In high school I was a much more avid reader than I am now. I read books like Dune, Asimov's robot series, The Shining, Salems Lot, and The Keep quickly, probably in a week or so.
At A&M I slacked off a bit, primarily reading at Christmas break or during the summer. I started reading It right after it was first published, right before I started my sophomore year in the Fall of '86. Probably got through a chapter or two. At the end of the semester, before I went home for Christmas, I read a bit more. Then on Christmas Eve, I read the rest of It - roughly 900 pages. All that night. Put it down in time for Christmas Day lunch. Toward the end of my time at A&M, I finally picked up The Stand during the summer of '89 and could not put that one down.
After A&M, I remember reading The Sum of All Fears in a week, and then, later, Jurassic Park in a day. I made short work of books like The Firm or Thunder of Erebus ... and then in the mid-90s, I pretty much quit reading. Picked it back up in the early 2000s, but now I am reading mostly non-fiction like The Rise and Fall of the Third Reich, Shattered Sword, or Pacific Crucible. I am re-reading Dune currently, much more slowly the first time I read that one.
