I read a book by Lynda Barry in which she recommended that every writer practice writing the alphabet regularly—that we get used to forming the shape of each letter, by hand, with intention—because they are each a magical symbol of expression imbued with a unique power.
I love her work and this particular theory always stuck with me. It's easy to get so used to writing (and speaking) that we take it for granted, but taking a step back, language is an invaluable tool. Thinking of great works of literature, and by extension films and plays, it becomes even more clear that entire worlds may adjust their values, perspectives, and actions because of expressions of language expertly crafted.
