I used to be a voracious reader in my youth. So much so that it interfered with my ability to get to school on time, my grades, and my (other) extracurricular activities. My parents learned quickly to not bother giving me any money, not even for emergencies, because I would spend it on books. They were never fond of my penchant for science fiction, claiming it was a frivolous waste of time when I should be reading classical literature or weighty philosophical matter (or doing homework). Once, my mother actually tore one of my books in half.
Then, at some point in grad school when I was reading tons of scientific papers all the time, I fell out of the habit of reading fiction. I no longer had days at a time to do nothing but read an entire book all at once. At the same time, reading became physically hard on me. No matter what position I sit or lie down in, some part of me gets stiff and sore - and by rotating through lots of different positions, my whole body ends up stiff and sore. It was like that in my youth, too, but I recovered faster back then. For a while I just read magazines instead (mainly Earth (RIP :( ), Discover, Smithsonian, and Science News), but eventually I stopped reading those, too.
Now I've been trying to ease back into reading. One of the writing groups I belong to started up a book reading challenge a year ago. Basically you declare how many you'll read that year, and then you list them as you finish each one. Last year I declared 12 (one per month seemed like a good way to ease back into reading when I hadn't read a thing for years) and ended up with 10:
1. Agent to the Stars - John Scalzi (sci fi)
2. Out of Thin Air - Peter Ward (science nonfic)
3. Memory of Running - Ron McLarty (mainstream fic)
4. The Paths of the Dead - Steve Brust (fantasy trilogy 1)
5. The Lord of Castle Black - Steve Brust (fantasy trilogy 2)
6. Sethra Lavode - Steve Brust (fantasy trilogy 3)
7. Core Performance - Mark Verstegen (nonfic exercise book)
8. Hellspark - Janet Kagan (sci fi)
9. Brokedown Palace - Steven Brust (fantasy)
10. Starcraft: Queen of Blades - Aaron Rosenberg (sci-fi)
This year I declared 12 again, and so far I have:
1. Color of Magic by Terry Pratchett
2. Dzur by Steve Brust
3. Old Man's War by John Scalzi
4. American Gods by Neil Gaiman
5. Thud! by Terry Pratchett
6. Going Postal by Terry Pratchett
At the moment I'm working on Hogfather by Terry Pratchett and On Writing by Stephen King. Pratchett is going faster. ;)
The fact that I started visiting the local library helps; I have a deadline to read them by, and then if I'm going to the library anyway to return books I might as well get more... Their sci-fi/fantasy section is only four bookcases, but at my current snail's pace they should last me quite a while. Also, I've learned how to read only a chapter or two at a time. It's much easier to come up with the time for that than two whole days of doing nothing else.
