“Let them” is the self-help mantra popularized by the podcast world’s favorite guru, Mel Robbins.

The creator and host of the chart-topping series — The Mel Robbins Podcast — started her career as a criminal defense attorney before pivoting to self-help speaking after her 2011 TEDx Talk went viral.

The talk, titled “How to Stop Screwing Yourself Over”, has now been viewed more than 33 million times and Robbins has written more than 10 books inspired by her journey of becoming more confident and fulfilled.

Her theories — from the “five-second rule” to the “high five habit” — aim to improve the lives of others, with fans praising her no-nonsense and frank approach to advice.

Her latest, the “let them” theory, has taken on a life of its own on social media, with videos of Robbins explaining the mantra garnering millions of views. Some enthusiasts even have tattoos of the motto. She has since released her book on the matter, The Let Them Theory, in December 2024, which has been on The New York Times best sellers list for 15 weeks.

For the uninitiated, “let them” is all about releasing control and detaching from the need to change or manage other people’s actions, opinions, and choices. Sounds blissful, but you may be wondering whether it works in practice. Here’s where to buy the book and subscribe to the principle.

If you’re feeling stuck, overwhelmed, or frustrated, she claims that the problem isn’t you, instead the power that you give to other people. According to Robbins, “let them” will set you free.

Using her signature no-nonsense, science-backed approach that has made her name, Robbins’ latest book shows how you can apply the mantra to eight key areas of your life. Complete with anecdotes from her own life and relevant research in psychology, neuroscience, relationships, and ancient wisdom, it promises to help you unlock your full potential.
