In this episode Nate and I breakdown the lessons we learned from listening to Episode 412 of the Tim Ferriss podcast with guest Josh Waitzkin.  Josh is the author of The Art of Learning, one of our favorite books, and has a great approach to the learning process. On Tim's podcast, Josh essentially asks the question "What holes do we have in our mental models for learning?" from the perspective of his new hobby. We try to apply the same questions and perspectives to climbing.
