I particularly despise people who express themselves poorly in writing.
Considered to be "one of the greatest works of Japanese literature" The Pillow Book is a lovely poetic journal filled with all sorts of observations, gossip, lists, poetry and prose from a Court woman in Japan in the Heian period.
Because I was doing a lot of journal reading and writing last semester my adviser recommended I read this. How insightful this book is! Beautiful reflections but also humorous entries.
