The building blocks of understanding are memorization and repetition
TL;DR: Study foundational blocks by repeating then until you understand. Keep repeating as you build knowledge and move to "harder" things.I like the message, but not the messenger.Articles like this, in my point of view, fail to delivery their messages in a better way because they are simply too long and with too much noise for my taste.The point he is trying to get across could be explained in a simpler way without the necessity of explaining how he went to the army, what he did there and all his personal history.All this information is completely irrelevant to the main goal of the article and turn it into a boring story instead of useful piece of practical advice.
