Each song has its own secret that's different from another song, and each has its own life. Sometimes it has to be teased out, whereas other times it might come fast. There are no laws about songwriting or producing. It depends on what you're doing, not just who you're doing.

I think that one of the nice things about the Yellow Submarine movie is that it seems to be perennial. People enjoy watching from each generation. And it was like the Beatles themselves. You know the Beatles seem to find new audience each time another generation comes along.

Talking about dreams is like talking about movies, since the cinema uses the language of dreams; years can pass in a second, and you can hop from one place to another. It's a language made of image. And in the real cinema, every object and every light means something, as in a dream.

There is a vitality, a life force, a quickening that is translated through you into action, and because there is only one of you in all time, this expression is unique, and if you block it, it will never exist through any other medium, and be lost. The world will not have it. It is not your business to determine how good it is, not how it compares with other expression. It is your business to keep it yours clearly and directly, to keep the channel open.

I always try to keep that feeling of being on the edge. I'm afraid of knowing too well and seeming mechanical.
