Recommend me a book, that will change my life

I want you to recommend me books, that changed your life. I want to read these kind of impactful books. Of course you don't know what will change mine, but yours might, so tell me please!

I don't care for the type of book. Since this is a very personal question, even if it is something that might seem stupid for some, tell me nevertheless.

I hope there is something for me among these. Thanks in advance!
