If you are a beginner, please don't think about anything else for the time being, learn from the ancients wholeheartedly, and then ask for luck. To put it mildly, there are many things in art that can only be understood but not expressed. The key is to feel and understand for yourself. See more, think more and practice more. See how others write; Thinking about why others write so well and how I can't write well; Finally, apply what you have learned to your own work and practice it repeatedly. In this way, I think you will make progress.
Even the most accomplished calligraphers in the contemporary era, their fine works are not "achieved overnight", they are all painstakingly obtained. One minute on stage, ten years off stage.
