Part of the issue of achievement is to be able to set realistic goals, but that's one of the hardest things to do because you don't always know exactly where you're going, and you shouldn't.

Any society begins by realizing that together, by helping each other, you can survive better than if you fight each other and compete with each other.

Part of the reason my friends and I became successful is that we were always helping each other.

If you want to be successful in a particular field or endeavor, I think perseverance is one of the key qualities. It's very important that you find something that you care about, that you have a deep passion for, because you're going to have to devote a lot of your life to it.

I thought it [Star Wars] was too wacky for the general public. Right or wrong this is my movie, this is my decision, and this is my creative vision, and if people don't like it, they don't have to see it.

It wasn't long after I began writing Star Wars that I realized the story was more than a single film could hold. As the saga of the Skywalkers and Jedi Knights unfolded, I began to see it as a tale that could take at least nine films to tell - three trilogies - and I realized, in making my way through the back story and after story, that I was really setting out to make the middle story.

A movie is never finished, only abandoned.
