Envy can be useful if you listen to it, says new book

Envy may be more helpful than its bad reputation suggests, argues social scientist and life coach Dr Stacy Kim in her new book, Envy. She says unexamined envy leads people astray, but paying attention to it reveals our deeper goals and what feels within reach, since we tend to envy people similar to ourselves. Kim credits sibling rivalry with pushing her through a fast-tracked PhD.
