Personally, I have always been terrible at writing, and I didn’t develop it until I was in high school. My experience: tracing is almost completely useless; just copying has little effect. It’s useless to just buy copybooks and follow them by yourself, whether tracing or copying. If you want to buy, buy textbooks - they should have content that explains to you the art of calligraphy, structural arrangements, and the principles and methods of strokes. It is best to have a teacher to explain, comment and correct you, and to have someone around you who is good at writing. If you have any problem with the structure of a character, you can always ask for advice - I had a hard-tipped calligraphy class at school and met a good teacher by chance. A classmate changed my handwriting because of his beautiful handwriting. I originally thought that my handwriting was hopeless and I had to give up.
You can definitely practice it at the age of 23, and it will be no problem at 53. You just have to find a way to understand the structure of the characters and how to write them. It’s best to have someone you can consult at any time.
