Michelle Obama was honest with her readers during an appearance at Barclays Center in Brooklyn on Saturday night for her Becomingbook tour.
Former US first lady MichelleObama said she has been "moved, touched and inspired" by London schoolgirls as she returned to a secondary school in the capital that she first visited in 2009.
"That whole 'so you can have it all.' Nope, not at the same time", Obama said discussing Sandberg's business and life strategy.
During her husband Barack Obama's time in office, Michelle pioneered a number of initiatives during her eight years in the White House, with a special focus on children's nutrition and health.
"I love it. She can say whatever she wants now".
But many were delighted at the glimpse of a more casual Obama, perhaps freer now than in the White House years.
Hearing Michelle Obama speak against the practicality of "having it all" is uniquely satisfying because she is a woman who seems to be the living embodiment of having it all.
Obama shared her vivid memories of not fitting in when she was a working-class girl in Chicago because she was so determined to be the best student, to always work hard and learn as much as she could.
Obama said it was important to give young people a reason to hope, particularly in the current divisive political climate.
Michelle Obama tells London school she still has imposter syndrome
According to reports, Obama quickly apologized for using the expletive, telling the crowd: "I thought we were at home, y'all".
Her comments about making a marriage work and focusing on a satisfying career, quoted by United States news site The Cut, clearly struck a chord with the crowd.
And last month, her memoir broke sales records to become the best-selling book released this year, just 15 days after being published. I was gettin' real comfortable up in here. "And so, overall, we are not seeing a major increase in female leadership in any industry or in any government in the world, and I think that's a shame".
"And so then it's time to go to marriage counselling".
"People are like, 'Oh, why'd she talk about marriage counselling?'" she continued. All right, I'm back now.
In fairness, she also knows what life is like in the public eye.
She also spoke of the importance of building support systems.
Obama, 54, was speaking to Good Housekeepingmagazine when the topic of the Duchess of Sussex came up. But her words have an element of truth that Sheryl Sandberg's optimistic ideology about "leaning in" to have it all doesn't take into account.
