Intellectual Flexibility

There is a difference between what you think it should happen and what ultimately happens, especially in the short-term perspective where supply and demand are defined not by fundamentals, but by fear and greed.

However strongly you believe in something and however coherent the case is, you need to be:

(1) willing to accept that you might be wrong, and

(2) able to take the position off even though you might not be wrong in the medium-term sense.
