Greg Heffley: A Life is a fictional book imagined by Greg Heffley and its only appears in The Ugly Truth. Greg thought if he becomes "famous and rich" he would write this as his autobiography. The main idea is if reporters ask Greg about his childhood he could just give them this book to know stuff about his childhood. Greg also thinks that by then he would forget the name of Rowley.
