What it's about

Mel Robbins's idea is simple: when other people do things that frustrate you, let them. Let them leave you out, judge you or make their own mistakes. Then 'let me': put your energy into what you control. She applies the idea to friendship, family, work, love and comparing yourself to others, with stories and research.

Why it's worth reading

It spent more than ninety weeks on the New York Times lists, one of the biggest self-help books of the decade. Readers say its simple phrase changed how they handle other people.
