This is a recording of a presentation that Tim Ferriss did while working on 4-Hour Chef. It covers the highlights of his learning strategy, and has a great Q&A session at the end.
I really wish the slides were included as a separate download, because I felt like I missed a few things there.
At this time, there is no audio book for 4-Hour Chef. I felt like this was enough to get me going until I have time to read the book.
