Kate Winslet says divorce can be good for children because it teaches them how to 'struggle'.
The Oscar-winning actress, who has three children by three husbands, said she had turned all the 'bad bits' into positive experiences.
She told Harper's Bazaar: "I think it's very important to teach your children to struggle on some level.
"I would honestly say that I wouldn't change a thing. Even all the bad bits. It doesn't matter how c**p times have been, they all matter, because those things shape who you are. And if you don't like who you are, well, then you're f****d really, aren't you?"
Kate married Ned RocknRoll, the nephew of Sir Richard Branson, in 2012 and they had their son, Bear Blaze, a year later.
Kate also has a 14-year-old daughter, Mia, from her first marriage to assistant film producer Jim Threapleton, and a son, Joe, 11, from her second marriage to film director Sam Mendes.
In the interview, the 39-year-old, ridiculed the idea that women can lose their baby weight in weeks, as some celebrities appear to do.
She said: "There's a big part of me – now, more than ever before – that feels a sense of responsibility for how other women view themselves.
"Take having the baby, for instance. Have I actively been on a diet to lose my baby weight? No, I haven't.
"I genuinely bloody haven't. I so didn't want to be one of those 'Oh, wow, she's back in shape after 12 weeks' women. When I read things like that, I just think, 'Oh, for f***'s sake, that's actually impossible'.
"Life is just too short to be spending time focusing on things like that. I want to keep my health and my sanity and be well fed and happy. I was nowhere near my pre-pregnancy shape when Bear was 12 weeks old – I was breastfeeding, apart from anything else, and hungry all the time – and nor would I have wanted to be.
"And, do you know what? My body will never go back to what it was, and I wouldn't expect it to after three babies."
Kate said she felt happier and calmer than ever and had stopped worrying about her appearance.
She said: "What is so gorgeous about being the age I am is that all the ridiculous angst I might once have felt about having a bit of cellulite, or being a bit puffy in the face, or whatever, has evaporated. I simply can't believe I ever spent any time wasting my life on that nonsense."
