Been there man. I did the same thing with Moby Dick, blew through it in a week and then my wife asked what it was about and I just stared at her. Total blank. You get in this mode where your eyes are moving but your brain is just waiting for something to happen. What helped me was reading out loud for a few pages a day, like actually hearing the words. Sounds dumb but it forces you to stop and sit with the sentences. Also try reading something way slower than you think you should. Like painfully slow at first.

I have to disagree that it's really about focus speed. My old S90 nails the focus fine but the shutter lag kills me every time, so I miss the sprint no matter what I do. Phone wins for me just because I can fire off a burst and sort through them later.

Had the same thing happen with a guy at a gym in Tucson. I was doing squats all wrong for months, knees caving in, and some old dude just walks over and tells me to point my toes out and sit back like I'm aiming for a chair. Took him ten seconds. My knee pain was gone in a week. The weird part is I'd been watching videos and reading forums for hours trying to fix it myself. Sometimes you just need a person standing there looking at your actual body instead of your idea of your body.
