Risk management is very important in trading. It is also good to avoid overtrading because trading is motivating when a trader is making money from it but later overtrading can let the day end bad for him.
To enjoy trading, if you have like $250 to trade, do not go more than $25 to trade. It will be better if you make it less than $25bif possible. Another problem most people have is the high leverage they are using.
Another thing is that traders should not think they can make money daily from trading.
