'I am quite free': Meghan Markle reveals quote that helps her block out 'vitriol and noise'

Meghan Markle has talked about how she copes with being attacked as a public figure, particularly when using her platform to discuss social issues. 

The Duchess of Sussex was asked about disparaging comments made about her by US President Donald Trump and having "mobs come at her" during her time in the limelight in an interview for Fortune's Most Powerful Women Summit. 

"It's about being authentic," Markle said, insisting: "If you look back at anything I've said... it's not controversial." 

"It's really interesting because what ends up being inflammatory it seems is people's interpretation of it."

The former Suits star said she often calls on a Georgia O'Keeffe quote she used to have up in her bedroom "many moons ago" to help her navigate the tumultuous nature of public opinion. 

"It resonates now perhaps more than ever, when you see the vitriol and noise that can be out on the world," she said. 

"It's: 'I've already settled it for myself, so flattery and criticism go down the same drain, and I am quite free'."

Earlier in the conversation, Markle warned of the dangers of "misinterpretation of something that was never there to begin with", in an apparent reference to the tabloid stories that are regularly published about her. 

"If you don't listen to all the noise out there and you just focus on living a purpose-driven life and you focus on knowing what your own moral compass is... there is always going to be naysayers," she explained. 

"The moment that you are able to be liberated from all these other opinions of what you know to be true, then I think it's very easy to just live with truth and live with authenticity and that is how I choose to move through the world."
