From the outset, I conceived Star Wars as a series of six films, or two trilogies.

The secret is not to give up hope. It's very hard not to because if you're really doing something worthwhile I think you will be pushed to the brink of hopelessness before you come through the other side.

I've always just followed my own course, whatever I found the most interesting to me at the moment. I've never had a real plan of, "I want to get from here to there, and I've got to do this."

I grew up in the era, 'Don't trust anybody over 30.' And, you know, I still feel that. Don't trust me.

Each time I do a trilogy it's ten years out of my life. I'll finish Episode III and I'll be 60. And the next 20 years after that I want to spend doing something other than Star Wars. If at 80 I'm still lively and having a good time and think I can work for another 10 years between 80 and 90, I might consider it. But don't count on it. There's nothing written, and it's not like I'm completing something. I'd have to start from scratch. The idea of a third trilogy was more of a media thing than it was me.

Suddenly everything came together in one place. All my likes, everything I actually seemed to have talent for was right there. I said, "Hey, this is it. I can do this really well. I really love to do it."

You have to find something that you love enough to be able to take risks, jump over the hurdles and break through the brick walls that are always going to be placed in front of you. If you don't have that kind of feeling for what it is you're doing, you'll stop at the first giant hurdle.
