Fight each round take it on the chin. And never never never ever give in.

I keep a diary when I have time to. I always know that I'm either having a great time or I'm very busy when there are three weeks of nothing in my diary. But I like to look back because in ten years to the day I can know where I was and what I was doing, and that's a nice feeling.

John [Travolta] and I have remained very close friends ever since we did Grease. When I was told that "You're the One That I Want" was named the #1 duet in history and, during a text chat with John letting him know he said "we should record a Christmas song." Of course I said yes.

I live my life in gratitude.

Singing at the Opening Ceremonies of the Sydney Olympics in 2000 was amazing and, probably the highlight of this decade is the opening of the Olivia Newton-John Cancer and Wellness Centre in my hometown of Melbourne, Australia.

The "Great Walk to Beijing" was a fundraiser for my cancer center. It was a three-week trek with fellow cancer "thrivers," including celebrities ranging from Joan Rivers to Leeza Gibbons, and Olympians.

It's very hard to get good songs because a lot of writers record their own; they keep the best for themselves.
