One important things I found missing in most books is the learning aspect.
Entertainment OK, but teach me new things especially the ones I need to survive the future.
I am not talking buy gold or btc, most ppl here know that. More advanced stuff. Gas pipelines for example as inflation hedges.
What did other people's do when they had to leave their belongings and flee dictators? How did they carry that value with them.
Emotional compartmentilization. Etc etc.. we need to learn thos as we will most likely need it.
