Don't take a person's font too seriously. Although I am 24, I can still change it. On the one hand, you can consciously copy some fonts and write your own words as neatly as possible. In fact, there is no need to write too well, as long as others can see it. The key is to practice your signature. On the one hand, everyone who wants to write your signature can see whose name it is. On the other hand, it is not easy to imitate. To say the least, technology is so advanced now that documents and manuscripts can be stored in computers and printed when necessary. Please sign your name at the bottom and write the date. If it is self-cultivation, you can practice calligraphy.
