The author doesn't touch on it but I think there is a larger theme here, which is that there are more than one path to your goals and most of the detail we obsess over end up not mattering as much as we initially thought. One example I like is the duolingo app. It will never turn you into a fluent or even good speaker of a new language. However, it makes you learn words which will more or less stick you after a while. Once you get in a situation where you need to speak that language you will suck, but do a one week immersion and all that preliminary work you did will supercharge your speaking ability.
