I totally get the struggle of wanting to read a great book but not having the budget for it. For 'The Self-Sabotage Book', you might want to check out platforms like Project Gutenberg or Open Library, which offer free access to a ton of books legally. Sometimes, authors also share free chapters on their websites or social media to hook readers.
If you're into audiobooks, Librivox has free public domain titles, though newer books like this might not be available. Be cautious of shady sites offering pirated copies—supporting authors matters, and many indie writers rely on sales. Alternatively, your local library might have an ebook version you can borrow through apps like Libby or OverDrive.
