Twitter is a global town square.

Managing by trying to be liked is the path to ruin.

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.

The way you build trust with your people is by being forthright and clear with them from day one. You may think people are fooled when you tell them what they want to hear. They are not fooled.

As you get ready to walk out under the bright lights of the improvisational stage of the rest of your life... be bold. Don't always worry about what your next line is going to be.

If there's ever an example of the importance of making bold bets and focusing on what you love, it's Twitter.

I was in Shanghai recently, where Twitter is blocked, and yet there were ads and billboards across town with hashtags on them.
