suggest me a book like letters to a young poet

i just finished reading it and i loved it so much i kept reading the letters back. it felt full of wisdom and suggested a serene form of introspection i appreciated very much. i also liked the letters format that made it feel that much more raw and personal.
i’m currently reading the replies and letters from the young poet!
if you can suggest anything of the same feel it would be much appreciated 🙂
