What book, fiction/non-fiction, changed a part of you and how?

Currently, my favourite non-fiction book is Can't Hurt Me by David Goggings. I've listened to the audiobook just because it has extra bits of dialogue between the narrator and David. It's a fascinating book about grit, perseverance and pain. What I like the most is that David is a real human and lives by his preachings. It's definitely not for everyone but it's a good reminder that whenever you feel like you gave it all, there's a little more that you can give. My favourite quote: “The Buddha famously said that life is suffering. I’m not a Buddhist, but I know what he meant and so do you. To exist in this world, we must contend with humiliation, broken dreams, sadness, and loss. That’s just nature. Each specific life comes with its own personalized portion of pain. It’s coming for you. You can’t stop it. And you know it.”
