I want to practice pen writing recently, but my foundation is not good. You can't learn even if you buy a copybook. My handwriting is small. How can I improve?

Anyone who writes beautifully is a person who has practiced hard, and no one is born to write beautifully. If you want to ask how to improve, it's actually very simple. You write a word on the copybook for one day, eight working days (exactly), then write another word on the copybook for one day, and so on. I can't believe you can't write well. I hope it helps you.
