Looking for books that offer a genuine perspective shift (No “hustle culture” or generic self-help, please)

Hi everyone,

I’m looking for recommendations for books that truly have the power to change how you see the world, something that offers a 360-degree shift in perspective.

To be clear: I am not looking for the "basic" self-help stuff often peddled by "hustle culture" gurus. I want something with actual substance and powerful ideas.

I’d love something that delivers these ideas through a story or narrative (fiction or memoir), as I find those more engaging, but I’m open to any genre as long as it’s deep.

I’m quite new to reading as a hobby, so I haven't explored the classics yet. Even though I’m a beginner, please don't feel like you have to stick to "simple" or "easy" books—I’m perfectly fine with dense or complex ideas if they are worth the effort.

That said, since I'm just starting to build the habit, I’d ideally prefer shorter books (or at least ones that aren't massive) to keep the momentum going.

What’s that one book that actually rewired your brain?

Thanks in advance!

I already read: The stranger (Albert Camus) and Animal farm (Orwell)
