Scott Young talks about these three ideas in a post about how to learn faster and better. I like this very much because the 21st century will be all about learning faster and better. So if we can master the process of learning, we will have an advantage in living better. It is also helpful because it shows us when we are wasting time. If we are not mentally mapping, practicing or teaching - we are not engaged in a learning process.
Series cognitive skills building stuff! Great!
