1, you must have a strong will to write well, that is, you are extremely eager to write super beautiful words. In other words, you should love calligraphy and take writing well as a pleasure. If you don't have this hobby and just want to write well for the sake of utility, I think you are far from being a good player. This is one of the reasons why many people force themselves to practice calligraphy many times, but calligraphy is always unsatisfactory.
2. It is best to write a good hand and have a certain talent for calligraphy. Of course, diligence can make up for it, and more efforts will have good results the day after tomorrow.
3. Choose famous copybooks that you like and appreciate (it is best to appreciate them yourself), read the copybooks carefully, carefully ponder the nuances of brushwork, word formation and composition, and copy them step by step.
4. In the process of learning copybooks, we must try our best to forget some bad habits (which you think are good habits that can be maintained) in the past, and carefully follow the copybooks, first draw red, then draw meaning, so that the effect will be better.
It is extremely important to regard ordinary writing as practicing calligraphy (it doesn't matter if you slow down), otherwise you will unconsciously return to the previous routine and get nothing.
6. Finally, writing is a long-term process (some calligraphers practice all their lives), which cannot be completed in a month or two. Remember not to be passionate for three minutes, but to persevere (even if you are tired after practicing all day), so that you can succeed.
