I wonder how or if my writing would improve if I knew multiple languages.
Haruki Murakami translated his first book into English, then back into Japanese when he first wrote it in order to simplify his style. I wonder if it added new ideas to it as well.
There must be some ideas that are easier to express in other languages, so knowing that language might open new avenues of thinking. Maybe there are some ideas that are only born in certain languages at all…
The answer is obviously to learn every language and find out!
