Stanley Druckenmiller

I believe that good investors are successful not because of their IQ, but because they have an investing discipline. But, what is more disciplined than a machine? A well-researched machine can make many average investors redundant, leaving behind only the really good human investors with exceptional intuition and skill.

Part of my advantage is that my strength is economic forecasting, but that only works in free markets, when markets are smarter than people. That's how I started. I watched the stock market, how equities reacted to change in levels of economic activity, and I could understand how price signals worked and how to forecast them.

My grandma actually put me in girdles when I was around nine or ten because I had hips even then, and she didn't want boys to be attracted to me. Having hips meant you were a full-grown woman, and I was too young for that.
