Mary-Kate Olsen says working hard comes "naturally" to her and her sister Ashley.

The 30-year-old actress turned fashion designer admits her and her twin sister don't need "much time to think and ponder" but says the pace has changed since she married Olivier Sarkozy and became a stepmother to his two children.
Ashley said: "I've always been a worker. It has taken me a lot to figure out how to take a vacation."
Whilst Mary-Kate added: "I think we're lucky [working hard] comes quite naturally for us. We don't need so much time to sit and think and ponder. But then I have a husband, two step-kids and a life; I have to go home and cook dinner.
"I ride horses on the weekends. You find the thing that helps you relax and if you don't have it, you have to look for it. Or you get burned out and then you're not productive."
Both Mary-Kate and Ashley have decided to steer clear of social media and feel they have "stayed quite sheltered" as a result.
Ashley added to Net-a-Porter's The Edit magazine: "We don't dive into that world [of social media]; we don't have Instagram or Facebook.
"So we've never been connected to our customers or our fans in that way. We've stayed quite sheltered."
Meanwhile, Mary-Kate and Ashley's younger sister Elizabeth Olsen previously insisted she isn't "remotely as cool" as her sisters.
She said: "They have impeccable taste and what they make is mind-blowing. I'm not remotely as cool as either of them and I often feel like I don't have as many options clothing-wise as they are very petite."
And the 'Captain America: Civil War' star doesn't spend too much time on social media either as she thinks there is an increasing amount of pressure on young women because of the rise of social media.
She added: "With social media, there's this need to be constantly seen and approved by others.
"Everyone is their own publicist and it's such a self-aware world. For young girls there's a pressure to create an image of yourself, which might not be reflective of what you're dealing with internally. I find that scary."
