I think it was Jefferson who said something to the effect of “if you want to know what’s true, look at what all the great religions agree on”

Similarly, people have been writing about thinking for a looong time, so rather than jumping from framework to framework it’s good to read a few old books and see what the authors agree on.

I’m not an expert on what those agreements are, but off the top of my head:

-be more prepared than your competitor -master principles and you can select your methods -don’t have rigid tactics, things always change so adapt accordingly. -chain is as strong as its weakest link - etc
