You don’t become what you want. You become what you believe. — Oprah Winfrey on success
If you want to sell your books, you must truly believe in your books. What do they offer to others? Entertainment? Information? Education? Inspiration? Enlightenment?
You can give away your book if you don’t believe in it. If you do believe in your book’s value, sell that value. Don’t give it away. Sell it. You become what you believe!
