Serendipitous Reader v2.0

I liked the first Rosie book, and really liked the second one - but this one was very "eh". Not as funny or entertaining as the earlier two. I got through it but I'm done with Rosie books. 

The author of this book did the entire MIT CS curriculum in a year, then spent 6 months each, learning 4 different languages. Clearly, he's focused (and maybe a bit obsessive). I thought the book was interesting, with some good nuggets for how learning actually happens, though it dragged in places.
