i gobble up fiction books but i haven't found you can read "any" nonfic book in 7 days, sure pop junk like Ryan Holiday Stoic's book (sorry Ryan but you probably know that's a hustle) but if it's a deep substantive book in a new area, it takes time>reading a bit, doing a bit of the new thing, screwing up a bit, coming back and reading a bit more...don't laugh but I've spent weeks reading Steve Perry's Secrets of the Nikon Autofocus System...
