Avoid fixating on irrelevant details. - Ray Dalio

Much as I loved the job and the people I worked with, I didn’t fit into the Shearson organization. I was too wild. For example, as a joke that now seems pretty stupid, I hired a stripper to drop her cloak while I was lecturing at a whiteboard at the California Grain & Feed Association’s annual convention. I also punched my boss in the face. Not surprisingly, I was fired. But the brokers, their clients, and even the ones who fired me liked me and wanted to keep getting my advice. Even better, they were willing to pay me for it, so in 1975 I started Bridgewater Associates.
