Ray Dalio: I love global macro because it’s everywhere in the world, and it’s trying to understand how all the parts of the world operate.  I love it because it’s very, very practical.  I like the fact that people are making subjective evaluations of how good I’m doing, but I can measure myself down to two decimal points.  What’s my performance? It’s subjectively evaluated.  I like the fact that I can go long or short, so that there’s no such thing as good times or bad times.  Most people have an industry or a profession, and they have cycles to them.  In my case, I don’t have any cycles. I have no excuses, just it’s all on me.  I can make bad mistakes and that’s that reality.  I like that.  So it’s those elements.
