I've been searching all over the internet to find the name of a book by Aldous Huxley that I remember quoting in a paper I wrote in high school but I cannot remember the book or much of what it is about. I remember the quote I used had something to do with not worrying too much about the rest of the world/things you can't control, or it will drive you crazy. I thought it was Huxley but I could be wrong. I think the book had some type of war or dystopia in it, which may be part of why I think Huxley wrote.

Any help would be appreciated, I would really like to find this book.

If you Google "Books by Aldous Huxley", you will find indices and a synopsis of every one of his books.

“I wanted to change the world. But I have found that the only thing one can be sure of changing is oneself.”

“Ye shall know the truth, and the truth shall make you mad.”

From Brave New World
