What kind of experience is it for a girlfriend to know Taekwondo?

/kloc-started studying at the age of 0/9 and got a black belt at the age of 22. It is estimated that few of them learn later than me. In fact, the experience is nothing special, except that I am stronger and more independent than ordinary girls, and I am not afraid to go out to play alone at night. After all, it is rare to have a fight. I was not busy with my studies before, and I also participated in performances. Now the dog doctor is too tired to even go to training. Probably the biggest change is getting stronger. Courtesy, honesty and shame, patience and self-denial, perseverance. Once, I did one thing without doing anything, and I had no willpower. After learning Taekwondo, I did something for a long time. Before, I ran down 800 meters and died panting. After learning Taekwondo, I began to exercise regularly and my physique improved a lot. Moreover, it can bear hardships more than before. After all, after practicing Taekwondo at an advanced age, lacing is worse than death, and I have been injured many times. And more responsible than before. I'm a little timid. I always like to hide in the back when something happens. I get nervous when there are many people. When I first started practicing Taekwondo, I took a small white belt and hid behind my brothers and sisters. I was nervous for several days after taking the yellow belt test. Later, I slowly rose to the red belt, red and black belt, played many games, slowly learned to take responsibility, and was no longer nervous and afraid in crowded occasions.
