Miranda Kerr rocks a long-sleeved crop top and bikini bottoms on the December 2013 cover of Self magazine. In her first interview since her split from husband Orlando Bloom, the 30-year-old model talks about staying happy during life’s rough patches.

On being happy: “If I’m having a challenging moment, I jump for joy. Literally. After a minute, I feel better, and after a few minutes, I’m really happy. Everything else just drops off. It gets me out of my head and into my body, and it makes me feel present. Everyone has challenges. But if you know your strengths and expand on them, you’re going to radiate.”

More on being happy: “Happiness is a choice we make. You can wake up and say, ‘Oh, I can’t believe it’s so cold,’ or you can say, ‘Oh, wow, this is a great opportunity for me to try out my new sweater.’ No one can be consistently positive, but why not make the choice that makes you feel better rather than the one that drags you down?”

On her mantra: “One mantra I like: ‘I am a being of light and love, and I radiate that to everyone I meet.’ It helps me keep things joyful.”
