His life principle: pain plus reflection equals progress.
Know yourself, follow your pull, and make your work and your passion the same thing, while keeping money in mind for freedom.

Why does Ray Dalio think empires rise and fall?

He says history repeats in a big cycle driven by three smaller ones: the long-term debt and capital markets cycle, the cycle of internal order and disorder, and the cycle of external order between countries. When a leading power borrows and prints too much money while its people fight each other, it gets weaker, and a rising power can take its place.
