Stanley Druckenmiller

Once an economy reaches a certain level of acceleration... the Fed is no longer with you... The Fed, instead of trying to get the economy moving, reverts to acting like the central bankers they are and starts worrying about inflation and things getting too hot.

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.
