Principles: Life and Work

by Ray Dalio

In trading you have to be defensive and aggressive at the same time. If you are not aggressive, you are not going to make money, and if you are not defensive, you are not going to keep money.

if you work hard and creatively, you can have just about anything you want, but not everything you want. Maturity is the ability to reject good alternatives in order to pursue even better ones.

Don’t get hung up on your views of how things “should” be because you will miss out on learning how they really are. It’s important not to let our biases stand in the way of our objectivity. To get good results, we need to be analytical rather than emotional.

It is a reality that each one of us is only one of about seven billion of our species alive today and that our species is only one of about ten million species on our planet. Earth is just one of about 100 billion planets in our galaxy, which is just one of about two trillion galaxies in the universe. And our lifetimes are only about 1/3,000 of humanity’s existence, which itself is only 1/20,000 of the Earth’s existence. In other words, we are unbelievably tiny and short-lived and no matter what we accomplish, our impact will be insignificant. At the same time, we instinctually want to matter and to evolve, and we can matter a tiny bit—and it’s all those tiny bits that add up to drive the evolution of the universe.

The two biggest barriers to good decision making are your ego and your blind spots. Together, they make it difficult for you to objectively see what is true about you and your circumstances and to make the best possible decisions by getting the most out of others. If you can understand how the machine that is the human brain works, you can understand why these barriers exist and how to adjust your behavior to make yourself happier, more effective, and better at interacting with others.

To be effective you must not let your need to be right be more important than your need to find out what’s true.

One of the most important decisions you can make is who you ask questions of. Make sure they’re fully informed and believable. Find out who is responsible for whatever you are seeking to understand and then ask them. Listening to uninformed people is worse than having no answers at all.
