Although she works hard to be happy, recent times have been difficult for the model. She and her husband Orlando Bloom have confirmed their separation, although they are determined to remain civil for the sake of their two-year-old son Flynn.
Kerr insists being negative is just a state of mind.
"Happiness is a choice we make," she said.
"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?"
The model advises people to look after their bodies to help achieve true happiness. She watches what she eats, feasting on food such as lentil soup, pine nuts and kale.
Kerr also has a special saying she reminds herself of whenever she is feeling down.
"'I am a being of light and love, and I radiate that to everyone I meet.' It helps me keep things joyful,'' she said.
