Tell me, what's it like to play the violin?

I am a professional, but I also came all the way from a rookie. I used to practice the violin day and night. For decades, I practiced for 6-8 hours every day until I became numb, and many things became my body instinct. Skills that are difficult for amateurs, such as artificial overtones, left-handed plucking and bow throwing, are not a problem for us, and Paganini is also our daily etude. Now it's more about practicing the heart, polishing the style of play, and pure art study. On the contrary, I don't want to show off in front of people when I am a rookie, especially I don't want others to know that I am a professional, and I don't want to play the piano in front of people who play the piano badly. I feel embarrassed and depressed, but I don't like it. I have infiltrated into the blood and into the bone marrow. Because I love and cherish it too much, I don't want to show it easily and I don't want people to see it.
