Loses are certain when it comes to trading, it's not just all about winning all the time, infant I even see losses as motivation to tell me that am almost there, although its comes with emotional depression, heartbreak and so on, but what keeps me going is the motive of being discipline, patience and focused while trading, regardless I still maintain being consistently because you never can tell the trade that will eventually change one's life for good.
Just accept loss as a stepping stone to success, by correcting every mistake to improve and gives you a better and successful trading result.
Already remember that success is not just something you can get so easily as expected, you need to be self disciplined, emotionally fit, to manage and control risks to become a better trader.
Do well to limit your trading expectations because no matter how good you can be with your trading analysis, loss is inevitable, but if you are really learning from your mistakes and also consult other successful traders trade to learn and gain more experience from them, you cannot be using loss as motivation, instead as a reason to learn more and do better because trading is all about consistency and how you can adjust based on market condition and also not to be too relaxed with your trades because the market can change at any time.
Furthermore, if you are not too good in your trading strategies, you can be using risk management methods like the use of stop loss and take profit to minimize your risk especially if your capital is not big so that you can trade more and gain experience while you grow your trading capital.
