It depends how much time I'm spending on the computer, but most of what I do on it comes from the same love of the written word.
I used to read a book a day before I got really into online talk. I can still hit that in spurts, and if work is slow too. Like yesterday, I started a novel at 100 before bed (My Sister's Keeper by Jodi Picoult, very nice read BTW) and finished it right around the time I started closing my shift, 1400 or so.
In a year, I'd guess about 250-300, just depends on what else is going on.
Ooh, just saw the discussion edged a bit, so I came back. I don't consciously set any target for myself anymore, but I do or did used to feel like reading is, or rather should be, my number one leisure priority. Does that make sense? Sort of like, nothing else is really as worthwhile, even though I do do other things for enjoyment. That's part of the old identity set thing from childhood, I was always the smart one, the book worm and all that. Unfortunatley, it never has taken me anywhere like the old fam wanted it too. . . but still, it just seemed like reading was so important. . . like chatting online or singing karaoke or going out dancing was really just a lame fancy compared to the fact that I could have been reading instead and theoretically improving my mind.
I'm over most of that now, but it was the guilty type of thinking that used to lead me to be like "Damn, I've spent three days on this novel! I gotta hit it harder, get another one in soon!" It led me to set targets for a long time, and that still rears it's head in me now and again, but moreover, I've gotten to the point where I see being a fast reader as just a gift now, not an obligation to acheive any certain amount of books.
