When I was your age, we didn't have the Internet in our pants. We didn't even have the Internet not in our pants. That's how bad it was.

Twitter is a global town square.

Successful businesses measure and count things. I think that's a safe assumption on top of which we can drop the following hypothesis: unsuccessful business either measure nothing, the wrong things, too many things, or finally, they measure the right things but they don't communicate the measurements efficiently.

When youre doing what you love to do, you become resilient. You create a habit of taking chances on yourself. If you do whats expected of you, and things go poorly, you will look to external sources for what to do next, because that will be your habit. You will be standing there frozen. If you are just filling a role, you will be blindsided.

The beauty of Twitter is that more and more people are flocking to it because it's shrinking their world.

What is the thing that matters most to making progress right now?

Once in a rare while, somebody comes along who doesn't just raise the bar, they create an entirely new standard of measurement.
