Reading Faster

Hacker News:

I’ve always been bothered by reading. I love reading, but I’m never proud of how much book I’ve read.
One problem is with reading speed. If average reading speed is 250wpm, then a average book of 200,000 words would take more than 10 hours, and you have to take into account the opportunity cost and the time for breaks between concentrations, and if the book is less interesting but is mandatory for you OR it requires more careful reading(i.e. College textbook), it would take more time.

Another problem is with how much you can remember after a while. I have a pretty bad memory, I often forget almost all of the stuff I read from a book as time goes. Which means that it’s a waste of time to even read it. This year I’m trying to take notes and write summary after I read a book. But that doesn’t help you to read faster.

How to read more? Can I increase my reading speed somehow? Or is there better ways to grasp the idea of the book faster? Is there a way to train your reading speed?
