Acquiring the knowledge and applying it in your trading with a proper risk management strategy in addition to having patient with your trade can be a strong weapon against the market psychology which can be deceptive to new traders that  may have acquired the knowledge quite well but lacking patient with their trades, that at the event of unpleasant move of the market  against their trade they get too quick to take profit instead of being patient with their trade for the greater success of it that lies ahead with time. Some even out of fear exit the trade with a loss.
