If believing in yourself and going after what you want in life and realising your worth is ruthless and selfish, then I'm definitely ruthless and selfish.

When you break a sweat you just feel great. You've got your endorphins going. You feel better. You look better. And if you aren't able to get a workout in, try to find a steam room somewhere. You just look and feel so much better after a sweat.

You cry and you scream and you stomp your feet and you shout. You say, 'You know what? I'm giving up, I don't care.' And then you go to bed and you wake up and it's a brand new day, and you pick yourself back up again.

Girl power is about loving yourself and having confidence and strength from within, so even if you're not wearing a sexy outfit, you feel sexy.

I don't really believe in diets. I love food... If I deprive myself, I'm going to want it more. I snack on yogurt, raw cashews and cherry tomatoes.

Confidence comes with maturity, being more accepting of yourself.
