9 things successful people do differently by heidi grant halvorson was exactly what it sounds like, a book sharing nine habits that successful people do. and while the book itself was smaller than my left hand, it packs a punch leaving readers with a lasting impression. the premise behind the book is that people don’t succeed strictly because of who they are; more often, people succeed because of what they do. and this book provides the to-do to make you a more effective person when it comes towards reaching your goals.
