Don’t just pay attention to your job; pay attention to how your job will be done if you are no longer around. - Ray Dalio

my belief that having an ability to figure things out is more important than having specific knowledge of how to do something.

Make believability-weighted decisions. ...
Operate by principles ... that are so clearly laid out that their principles can be easily assessed and you and others can see if you walk the talk.

In my early years the psychology of the 1960s U.S. was aspirational and inspirational — to achieve great and noble goals. It was like nothing I have seen since. One of my earliest memories was of John F. Kennedy, an intelligent, charismatic man who painted vivid pictures of changing the world for the better — exploring outer space, achieving equal rights, and eliminating poverty. He and his ideas had a major effect on my thinking. The United States was then at its peak relative to the rest of the world, accounting for 40 percent of its economy compared to about 20 percent today; the dollar was the world’s currency; and the U.S. was the dominant military power. Being “liberal” meant being committed to moving forward in a fast and fair way, while being “conservative” meant being stuck in old and unfair ways — at least that’s how it seemed to me and to most of the people around me. As we saw it, the U.S. was rich, progressive, well managed, and on a mission to improve quickly at everything. I might have been naive but I wasn’t alone.
