I'd go further and say the ability to switch off the logical parts of your brain is essential when dealing with the financial markets. Trying to understand why the markets are doing what they are doing is not only a waste of time when trading, but can lead you badly astray. That's when you think you know what the market is going to do next, based on your research and rationality. In practice, it can and will ignore your rational conclusions and do whatever it likes.
