Keira Knightley would love to be more "positive".

The actress is currently promoting her latest movie Seeking a Friend for the End of the World and would like to be able to be more aware of true happiness, like her character Penny.

Her character's ability to live in the moment is what Keira liked most about the role.

"I'm not as positive as she is, though I'd love to be! But just the ability to go, this moment is fantastic. And actually be in a room and just be, I don't know, drinking a milkshake. And say: I'm really happy now.' And it's a quality I don't have, that you notice when you're sad," she told the UK edition of OK! magazine.

Keira also spoke about her culinary skills.

She admitted that unlike Penny, she isn't a "brilliant" cook, but her mother has recently started to teach her a few dishes.

"I'm alright. Not brilliant, but alright. My mum's a really good cook, but we had a really small kitchen, so she could never actually teach me any of the stuff that she made. But she's now starting to. I've gotten really good recipes, which are excellent," she said.
