2 main reasons for learning history:
1. Everything’s been done before. The details change but behaviors don't. The biggest lesson from the 100 billion (vs. 8 billion alive today) people who are no longer alive is that they tried everything we’re trying today.
2. Our personal experiences make up 0.00000001% of what’s happened in the world but maybe 80% of how you think the world works. We’re all biased to our own personal history.
