The best traders can put on a trade without the slightest bit of hesitation or conflict, and just as freely and without hesitation or conflict, admit it isn’t working. They can get out of the trade — even with a loss — and doing so doesn’t resonate the slightest bit of emotional discomfort. In other words, the risks inherent in trading do not cause the best traders to lose their discipline, focus, or sense of confidence.
If you are unable to trade without the slightest bit of emotional discomfort (specifically, fear), then you have not learned how to accept the risks inherent in trading. This is a big problem, because to whatever degree you haven’t accepted the risk is the same degree to which you will avoid the risk. Trying to avoid something that is unavoidable will have disastrous effects on your ability to trade successfully.
