Drew Barrymore: I'm an overachiever parent

Actress Drew Barrymore, who recently split from husband Will Kopelman, says she wants to be the best mother possible for her two children,

Olive

and

Frankie

. "I thought I knew what love was, but holy cow, I did not. I could never have imagined the kind of love I have for my children. I am who I am because of my daughters. I'm an overachiever parent, and not because I think I'm going to repeat the patterns of my parents," Barrymore told Good Housekeeping. Drew Barrymore's parents were 'total hippies'
Barrymore's own upbringing was less than traditional, a childhood she doesn't fear her children will share. "I've already broken that pattern in my life. But having grown up in the opposite way, I'm raising my children with all consistency, all protection. This is my chance to get it right." The 41-year-old actress says she focuses on earning her happiness. "Happiness is not this yellow, blithe, floating thing. It's something that takes a tremendous amount of work. There's a warrior aspect to being happy. You've got to fight for it. And only when you've got that kind of earned happiness is it really good."
