There have been many moments over the last year when I thought it was all over.

I've worked really hard, but it's definitely not been easy.

I would love to do well one last time in Melbourne and my dream would be to win Wimbledon and play in the London Olympics.

I've been practicing for a while now and physically trying to get in better shape as well after the injuries.

When I meet parents in my children's school, they say there aren't good films for kids to watch. I wonder about the lack of such films too. What do my kids watch?

We get emails from parents asking us what kale is because their kids are asking for it. That kind of extraordinary presence in the community is critical to the future of real food.

Obviously I ask my family and loved ones for advice here and there, but I kind of have a rule with the people I love that surround me - close family and close friends - that unless I ask for it, I don't really want advice thrown out.

It was not my wish to come into politics. I was not a public person; I preferred to spend my birthdays with family and friends. But the 2008 elections were fraudulent, so I decided to finance the opposition to make them stronger.
