Since our childhood we learn or get habitual to live in an environment which makes us feel good, far from our fear and in a comfort zone. This makes us feel happy and relaxed as a similar feeling occurred after success. And almost opposite situation occurs if we have to face a failure in our life. Failure took us out of our comfort zone, makes us feel angry, annoying, and eager to do something.
Everyone wants to be successful and there is no doubt in it but what will happen if we face failure and keep getting failure after failure. Well in my view it is good to be failed. Because if you failed in doing something, then you will totally out of your comfort zone, where you will either quit from the game or will love to work and keep working until success.
The same psychology is applicable in trading also, where failure are part of the game and they came to visit everyone, every trader. But those who are determined to be successful do not stop and frustrates themselves from any losing trade. They take a lesson from it and start to work for the next one.
Failure after failure must lead us to victory if we accept and learn from them, trust in ourselves and are determined to be successful.
