4. Purple Cow:
Are you having a hard time coming up with a product? Do you find it hard to market a product that so many others have already marketed so well? Well, that is why Seth Godin recommends in this book to never put a “me too” product on the shelves, but a product that no one else has put on the market yet. If you create a product that is different and innovative, you will not even need to market it! This book is great for entrepreneurs looking to start a business off of a brilliant idea.
