Stop complaining to become a great trader. When you experience a failure, of course we will complain, of course we will blame everything that makes us wrong. We turn on the system, we blame the indicators, we even turn on the brokers who don't know anything, even though it is what makes us lose. our own mistakes, maybe we were too greedy, maybe we were too emotional, maybe we used a big lot, we have to admit that, we don't need to complain, what we have to do here is learn to be sincere, learn to change all the characteristics of our mistakes so that they will be better in the future.
