It is impossible to know everything, but it is possible to always have something at hand that will help you learn new information and remember old skills... Any fighter of any style, studying a fight - attention, a fight, not a competitive aspect - knows and knows how to carry out meanness and deception, has immunity to them, achieving this immunity in constant practice... From yourself: grab me by the balls or poke me in the eye - I will tear you apart, and not because I got mad, but because the first rule of a fight is no matter how it hurts, make it doubly painful for the opponent, everything else then... Everything starts somewhere, and the path of safety along the path of survival begins with the desire to take the first difficult step...
