Stephen King's book - On Writing

I just have read Stephen King's book called "On Writing". It was an audiobook, voiced by the author himself. And I am must say, this audiobook is really nice one.

Firstly, it is easy to understand because the text is quite simple. Secondly, it is a great pleasure to listen to Stephen King's voice. I've read or rather listened to the book twice. For the first time I've got maybe around 40 percent of the meaning, and for the second time I hope I've got around 80 percent of what Stephen King tried to say to me in his book. And I noticed that I can understand English speech much better after all.

Probably, listening to audiobooks is more useful thing for improving listening skills than watching movies, because you can concentrate on (the\a?) speech only and you will not be diverted (better is distracted) by the visual picture.

You say "I have about 40% of the meaning" or "I got about 40% of the meaning".

Comment: I agree that it is a great idea to listen to audio books when you have reached a good level of English as you have. I'm learning Chinese and will do the same thing as you once it is good enough.
