If you can master your trading psychology, then you have done more than half of the work already because the market is you vs. you. The remaining side is a good strategy to help you in the market. The majority of traders fail early because of poor psychology; they are too quick to make profit, and even when they make the analysis, they are not too sure of it, so they kick out even before they can make big profits. To be a very successful trader, you need to develop a strong trading psychology and then have a good strategy to back you up.

With mentorship alone, you learn strategy; you need to do the extra work of mastering your psychology.
