Reese Witherspoon: 'I'm Much More Open Now' Than in My 20s

— -- Reese Witherspoon is looking forward to her 40th birthday in March, even if she'll have to figure out another way to celebrate it.

"I wanted to hike Machu Picchu. But then I was like, 'Wait, I did enough hiking last year,'" the star of "Wild" told the February issue of Harper's Bazaar. "I’m done with hiking for a minute."

Instead she's thinking of marking the occasion with friends and family in Nashville. "You know, live music, eating, kids," she said.

In the magazine's cover story, the Oscar winner said she has much more ease now than in her 20s.

"I’m much more open now. In my 20s, I was scared of everything," she said. "I didn’t know what my career was. I didn’t know why people liked my movies. I was wary of interacting with people. I was 25 when 'Legally Blonde' came out, 26 for 'Sweet Home Alabama', and 29 for 'Walk the Line.' And I was scared, really scared. Now I feel like a different person. It’s a great thing getting older. You are who you are; you say what you mean."

She's not afraid to use her voice in Hollywood either, having optioning two books, "Wild" and "Gone Girl," shepherding them through production and seeing both receive Oscar nominations. Currently, she has 30 projects in development -- 25 movies and five TV shows.

"I want to get a female perspective on film that would make my daughter [Ava] understand what it means to be a woman in a different way," the mother of three said.
