It’s a very interesting process (the process followed in the video) but also extremely complex, expensive, and time consuming. Over time and as I have aged I have learned that simplicity, not complexity, is in my opinion, what actually yields both more productivity and more profit on most enterprises and projects and endeavours. Therefore I tend to eschew complexity nowadays. Plus, complexity tends to be both highly redundant and very expensive. For instance if you want intact copies of each book in your library then you have to buy two copies of each book to execute this process.
Not that I don’t think this process would yield valuable results, especially the fact that he reviews books while his heart rate is up, etc. (his data absorption process) but my information preparation and absorption process is extremely simple by comparison.
