So, there's one guiding star, but each step along the way there's the next big mountain to climb, the next Big Hairy Audacious Goal. So, you want to think of it as that every time you're about to get to the top of the mountain, every time you're about to summit, you say to yourself, “What's the next mountain? What's the next Big Hairy Audacious Goal?” so that you're always saying, “Oh, my goodness, that was really hard, but this next one's going to be even harder.” Then when you get to the top of that one, you look at it and you say, “Boy, that one was really hard, but the next one is even going to be harder still.” You just keep setting BHAG after BHAG after BHAG—Big Hairy Audacious Goal. And people wonder, “How do you stay out of complacency?” Well, if you just keep setting goals that are really huge, you will not be complacent. They will make you better.
