The Resident Evil actress and her partner Paul Anderson welcomed Ever's arrival in November 2007 following a five-year romance.
"She's the biggest single teacher in the world for me," Jovovich told the Liverpool Daily Post. "When you have a baby, the baby becomes so important that only really tangible problems become important rather than all these emotional concerns that you have before.
"Pre-children you create so many problems for yourself, like, 'Am I ready for this audition?' and you fret loads about whether you're good enough, but now I have Ever, it's not such a big deal.
"Even if I don't get the job, I know I'm going to be really busy as a mum. And even if I didn't do another film again, being a mum is a full-time job."
Jovovich recently announced plans to marry Anderson on August 22.
