Words are never divided into good-looking and ugly. What you like is skill, and what you dislike is art. As long as you write each word carefully and express your own personality. When I have free time, I just write random words by myself. If I feel something is not good, I can write it again a few times until it is pleasing to my eyes. Writing is something that accumulates day and night. As long as you are determined, your words will be beautiful.
