We don't know who we are or why we are here, we can only guess at that. But we see that for our survival in this world, we have the most necessary qualities for this. But in the social environment, we have been implanted for generations with humility, submission, and fear, so that it is postponed at the genetic level. Thus, our inner strength is suppressed for many generations. The word " can't” is just for such people with a depressed psyche. Ancient rituals, shamanic rites, all of them were aimed at training the psyche. The North American Indians were finally exterminated only when all the shamans were destroyed. It was shamans who made warriors invincible, they so pumped up their psyche that they were not afraid of anything, and if a person is not afraid of anything, it is impossible to defeat him.
In sports, in business, in any kind of activity, you need a strong character and fortitude everywhere. This is all, the mental state of a person that can be trained or suppressed. Manipulation of people is the artful application of psychological knowledge in order to obtain personal gain. And although I have repeatedly been convinced that all people can be manipulated, regardless of their mental state, yet people with weak psychics are subject to this to a much greater extent. You can pick up a key for any person, but a weak character is just an open door. But a person with a pumped-up psyche is an insurmountable wall. The character must be tempered, the psyche must be trained.
Of course, there are people who are okay with this, they are not depressed people, they are adapted to life. They are like raw stone, nothing is impossible for them. Everything in this life lends itself to training, and the psyche is no exception. If you were humiliated, suppressed, oppressed as a child — it does not matter, believe me. You can become a strong person, you can change and move away from your past, if only you stop putting up with your weakness and start working on yourself. You can do this yourself or with the help of a good specialist.
