Principles
by Ray Dalio
Dalio's principles for life and work, built from running the world's largest hedge fund: radical truth, radical transparency, believability-weighted decisions, pain plus reflection equals progress. The life section is strong; the work section describes a culture most organizations could not adopt. It is long and systematic, with a short version in the front.
Read it if…
you want a rigorous, systems-level approach to decisions and are willing to confront your weaknesses on paper.
Skip it if…
you want warmth or brevity; the book is an operating manual.
Three things you will actually use
- Pain plus reflection equals progress; reflect.
- Write your principles as you discover them.
- Seek the most believable people, not the most agreeable.
Do this first
Write down your most recent painful mistake, what it reveals about you and the principle it suggests.
Our verdict
Thorough and demanding; the first hundred pages carry most of the value.
