Now that that's out of the way, it’s time to say a little about my method.
I’m going to use normal books—real books. I’m going to expose myself to a lot of interesting text, lightly, at the speed of sound.
By that, I mean that usually I’ll listen to the audiobook while I read so as to cause me to skim lightly and quickly along the sentences.
So that’s 2 things together—actually 2 times 2, because I’ll get the books in 2 languages also.
One commonly available resource is Harry Potter—stuff to watch, read and listen to.
