Any of the best traders (the probability thinkers) could have just as much negative energy surrounding what it means to be wrong as the typical trader. But as long as they legitimately define trading as a probability game, their emotional responses to the outcome of any particular trade are equivalent to how the typical trader would feel about flipping a coin, calling heads, and seeing the coin come up tails. A wrong call, but for most people being wrong about predicting the flip of a coin would not tap them into the accumulated pain of every other time in their lives they had been wrong.
