    "When you're young -- 18 or 19 -- ... work as hard as you can. ... Now I'm a woman, and because I gave it my all, I can focus on my marriage. ... I can be the mother I want to be and dedicate myself to my children."

Still, Beyoncé's not going to stop working! "I want to make my job a part of my lifestyle so that I always enjoy what I'm doing," she says. Love it! Modern-day woman!

Beyoncé and Jay-Z, 41, married in 2008.
