'Let them': With two words, author Mel Robbins has started a movement

With two words, Mel Robbins has started a movement.

Even if you don't know her name, chances are you'll recognise the bright green cover of her book The Let Them Theory.

Released in December, the self-help book is already a best-seller that's been dissected in book clubs around the world and catapulted the author and podcaster into Oprah's stratosphere.

Speaking with David Campbell on Today Extra, Robbins explains the book is a mindset tool that "shows you immediately what's not in your control and what's in your control".

The way that you use it is super simple. If you ever feel frustrated or stressed out or annoyed or hurt or bothered or worried, just say the words 'let them,'" she explains. 

"You're going to notice that other people's behaviours and opinions constantly stress you out. And when you say 'let them', you are detaching from the one thing in life you'll never be able to control, which is other people."

"And then you say 'let me remind myself [of the] only three things I can control: what I think about this, what I do or don't do, and what I do in response to my feelings."

This detachment, she says, allows individuals to take control of their emotions and responses, leading to a more proactive and fulfilling life.

"I learned absolutely everything from screwing up my own life," she admits, explaining the book is a way to help other people avoid the same mistakes.

"You need your time and energy and focus to be able to show up for the people and things in your life that are for you."

Robbins wrote the book with the help of her 25-year-old daughter Sawyer. 

"It healed our relationship … we learned to say 'let them'," she says. 

"When someone you love frustrates you, learning how to give them the space to be who they are and love them as they are, this actually brings you closer to people."
