Poor Charlie's Almanack
latticework. compounding fundamendal science knowledge and braiding them constantly like a latticework and that making your backbone on life.
he didn't seem the money person (he is eventually the most money person yes) but rather like how to read, research, understand any world is working underneath. it felt like the whole fortune is just a side effect of his dedication to "understand" how anything creates the value in bigger picture.
his examples and how to look into investing. like i don't remember the exact examples the book gives but e.g to invest on nvidia, one should know how the semiconductor works, how could logistics could be impacted by which geographic conditions, what historical conflicts those producing factories or governments faced before or expected, what is that material how it works in chemical level, why it's niche, what other alternatives etc. like you need to make sense of why that company is competive by the given restrictions, what niche it applies.
his look into biology was also weirdly what stuck with me. like how to think about primitives like the computing. ants having less neuron density than human brain making them less cognitively capable. this literal take made me lookup why elephants are not smarter but science has scienced on that :d anyways this was an interesting read.
