This may sound a bit “fluffy”, but it really is rooted in logic; if you make mastering your chosen trading strategy your all-consuming desire, instead of making money, you will naturally reduce the probability of committing emotional trading mistakes because you will not be focused on money (focusing on money induces emotional trading). You aren’t going to fully develop your trading skills or your ability to read price action by constantly thinking about how much money you can make on a trade, conversely, you aren’t going to make any consistent money in the markets until you develop your trading skills.
