How does martial arts affect the character and thinking of a person?

A responsibility
Since single combat is an individual sport, it means that the responsibility lies with itself.

Did you miss training due to a disrespectful reason? Distracted by extraneous thoughts, when the mentor took apart the nuances of the work? Halturil, wringing out not at full strength? Victory and defeat depend on you and only you.

freedom
A soldier is an independent person, so he is free to show creativity in competition with a rival, which extends the range of possible options when solving a particular task in life.

Yes, of course, there are established codes of practice, which are adhered to by practice, but if everyone acted according to patterns, without fresh experiments, then single combat, as well as life, would be boring and tedious.

Patience
Physical pain is extremely unpleasant, but without it martial art is unthinkable, even doing playful, joyful capoeira, you need to understand that strokes and injuries are inevitable.

Perseverance
Medals, cups, letters - it would seem trash, but so it is, if viewed from the standpoint of materialism. However, these things are not just the decor of the wall, but bear a symbolic character, indicating the degree of persistence of the athlete.

So, in many martial arts there is a system of belts, that is, ranks, which stimulates fighters to continue to improve themselves.
