When a plane lands in the Hudson and there's a Twitter user on the ferry taking a picture of it, Boom. That's it. The water is still splashing. Here's the photo of the thing.

I think we definitely want to focus on the simplicity aspect because it's something that's built into the culture even here at Twitter. Constraints inspire creativity.

I've probably overused this analogy of a flock of birds moving around an object in flight, but, in reality, it's so simple, real time communication of individuals that allow for this super organism type of organism to happen.

Lesson number one: opportunity can be manufactured. Yes, you can wait around for the right set of circumstances to fall into place and then leap into action but you can also create those set of circumstances on your own. In so doing, you manufacture your own opportunities. This has helped me immeasurably.

When you hand good people possibility, they do great things.

Inventing your dream is the first and biggest step toward making it come true.
