If you spend too much time thinking about a thing, you'll never get it done.

Knowing is not enough, you must apply; willing is not enough, you must do.

What's money? A man is a success if he gets up in the morning and goes to bed at night and in between does what he wants to do.

Never tell people how to do things. Tell them what to do, and they will surprise you with their ingenuity.

If you want to do your duty properly, you should do just a little more than that.

To know what people really think, pay regard to what they do, rather than what they say.

I have been impressed with the urgency of doing. Knowing is not enough; we must apply. Being willing is not enough; we must do.

I can't stop, mate. I'm on fire. I wake up in the morning and I'm on fire. I just can't do enough. It drives me crazy that I've got to go to sleep; you know, can't I film something at night?

Tell me if anything was ever done. This was written in his notebooks in despair of so many projects that were never completed.

If you always do what interests you, at least one person is pleased.

You can't try to do things. You simply must do things.

Figuring out what the audience expects, and then doing something different, is great fun to me.

To do is to be.
