Not looking for a pure self help book.
I’m interested in a non-fiction, (preferably) instructional book that explores how one might change their personality. I can imagine some books might approach the topic as it relates to being an actor or a spy. I’d prefer something with practical instruction and not so much hypnosis/pseudoscience if possible. Am open to looking into any and all suggestions, however.
Thank you!
