Why shoot for the moon? It matters because when you try to do something radically hard, you approach the problem differently than when you try to make something incrementally better.

Here is the surprising truth: It's often easier to make something 10 times better than it is to make it 10 percent better.

When you try to do something ten per cent better, you tend to work from where you are: if I ask you to make a car that goes 50 miles a gallon, you can just retool the engine you already have.

If you're shooting to make the world 10% better, you're in a smartness contest with everyone else in the world - and you're going to lose. There are too many smart people in the world.

Making a moonshot is almost more an exercise in creativity than it is in technology.

Wouldn't it be awesome if we had a jetpack that wasn't a death trap? The problem is that it is going to be so power inefficient. I just couldn't live with that... it would be as loud as a motorcycle.
