Gwyneth Paltrow said the "shine of acting" wore off following her Academy Award win in 1999, blaming working for "rough boss" Harvey Weinstein and intense public scrutiny.
Paltrow, who set up her lifestyle brand Goop in 2008, has admitted she became disillusioned with the film industry at a young age and realised she did not "love acting that much as it turns out".
Speaking on SiriusXM's Quarantined With Bruce she said: "I sort of felt like, well, now who am I supposed to be? Like, what am I driving towards?"
Paltrow, whose film roles include Shakespeare in Love, The Talented Mr Ripley and The Royal Tenenbaums, said "part of the the shine of acting wore off" as a result of the "intense public scrutiny" she was under.
The mother-of-two added: "Being a kid who's living every breakup on every headline, being criticised for everything you do, say and wear.
"And also, it's so transitory, you're always all over. It's hard to plant roots. I'm such a homebody, you know me, I like to be with my old friends and cook and squeeze my kids. I don't want to be alone in a hotel room in Budapest for six weeks. It's just not who I am."
Paltrow also said working for Weinstein - who she has since accused of sexual harassment - made matters worse.
"If you compound those things with the fact that like, you know, to be totally candid, I had a really rough boss for most of my movie career at Miramax.
"Like, so you take all those things, you're like, 'I don't know if this is really my calling."'
Paltrow's recent film roles include appearing in the Marvel movies as Pepper Potts.
