True, a teacher should aim to transfer usable knowledge and not just share a list of how much they know. Perhaps most content writers opt to play it safe thinking their personal experience is not a one-size-fits-all and end up with a fuzzy picture trying to just share basic rules and principles.
One of the reasons why people would rather watch YouTube videos rather than read a book of that form is because watching a video would relatable to a picturesque feeling would impact knowledge rather differently.
People prefer to watch videos over reading a book because YouTubers will fill them with "how" knowledge which is what most people want to hear. Admittedly, I'm guilty of that too, we want to find quicker practical ways to get us where someone is now financially and most finance books I have read have sets of rules. The practical knowledge one gets from youtube is very appealing but relative too if one is to extract from it to develop personal finance. It can be tricky if one doesn't have an understanding of why it worked which most financial books aim to establish first by setting up basic financial principles.
Those principles are not just mere sets of rules, they're mostly s consolidation of different human experiences but it can be overwhelming to the reader to read a whole chapter reflecting on inflation and scenarios while the book title was selling you how to invest. What we turn to miss in those books is the opportunity to explore different financial scenarios and how to incorporate things that are outside our control such as inflation to fit our day-to-day financial choices. A picturesque youtube video may miss out on this knowledge.
Most personal financial lessons we can only learn through doing and experiencing and one may stand a better chance to customise what works for them if they have an understanding of why financial rules were set and when to apply them relative to our financial needs. I guess this is the part where indeed a great teacher is needed to translate financial principles into a language or scenario people can understand and relate to.
This is absolutely true, however, the most usable knowledge are the knowledge we find very common, however, not having them at all can be detrimental to our learning process. I think I learnt from some of the most ordinary things of life and we cannot completely sell knowledge in a raw form because people have different mental capacities and I guess from a teacher's in perspective, this feels relatable. So if knowledge is not relevant I don't consider it's Importance. So knowledge to me is important based on the impact and usability and not some old principles. Knowledge becomes obsolete with time and hence we have to replace them. However the varoius experiences we have is evergreen and inasmuch it might not feel special to us, there are people who would want to learn from them.
Thanks for the amazing comment
