Shailene Woodley loves a whole lot more than just acting.

The 19-year-old Secret Life star tells Teen Vogue, “As an actor, you probably book only one out of 150 auditions. I never took rejection personally, because acting wasn’t the only important thing in my life. I’m really into environmentalism–I feel a connection to nature.”

Check out some of Shai‘s best kept beauty secrets:

– Shailene changes her pillowcases every other day. “The hair products they use on me during shoots can get onto it and clog my pores.”
– Keeping the water bill down: “When I’m in the shower, I turn off the faucets while I’m washing my body or shaving–I just keep a cup of water there to rinse the razor.”
– She uses extra-virgin coconut oil as a body moisturizer: “Not only is it all-natural, but I don’t have to wear a fragrance, because I smell like a yummy macaroon!”
