in school you learn how to do 2 + 2 and understand why it is 4. its not the actual answer that is the goal, its the understanding of why it is so and how the steps are applied to get the answer. knowledge layered on knowledge happens over years of learning, but eventually you know some stuff about things that people already learnt before you. as the saying goes- this isn’t rocket surgery, people!

make it real for your dad - every chance you get, capture the price of a few things and chart it out over time… actual real evidence that you collected yourself is harder to refute than a graph produced by anonymous sources online.

feel like thats a notepad++ problem? in general, breaking it out into manageable human ingest-able chunks is A Good Idea
