Mel Robbins has a gift for capturing simple ideas that make a huge difference when applied consistently.

Following The 5 Second Rule and The High 5 Habit, she now introduces The Let Them Theory. While I found The 5 Second Rule interesting but repetitive, The Let Them Theory uses the same formula but with much better results. Because the Let Them Theory is so widely applicable and as every context raises different questions, this book didn’t feel as repetitive.

The core ideas aren’t new; focusing on what you can control is a hallmark of ancient philosophies like Stoicism. However, the way Mel Robbins presents these ideas makes them accessible to a larger audience. By putting of lot of herself — her personal stories, her failures, and her anecdotes — she makes it easy for the reader to relate.

The book works. The topic is so relevant that you will find yourself thinking about it even when you aren’t reading it.

I enjoyed reading it. Every chapter brought new perspectives, even on topics I was familiar with. I found the chapters on adult friendship particularly insightful. It’s the kind of book I would have loved to have read years ago while discovering the complexities of modern adulthood.

The Let Them Theory is easily one of the best self-help books published recently. By letting them, you finally find the focus to be who you really are.
