Leadership is a choice. It's not a rank, it's a choice. I know many people who are at the top of their organization who have authority. We have to do what they say because they have authority over us. But they're not leaders. We wouldn't follow them. They may be at the top of the company but they're not leaders.

I'm very prescriptive about who I work with. I'm very clear about what I believe. If they believe what I believe I will work with them. If they say things like, "Convince me we should do this." I walk away.

The single best machine to measure trust is a human being. We haven't figured out a metric that works better than our own sort of, like, 'There's something fishy about you.'

Remember to connect with people now and then. In fact, pick up the phone, right now, and call a friend for no other reason than to say hi.

Our vision is only actionable if we share it. Without sharing, it’s just a figment of our imagination.

The goal is not to be perfect by the end. The goal is to be better today.

Too many people write books as a calling card.
