If I had to reduce the responsibilities of a good follower to a single rule, it would be to speak truth to power.

The ability to plan for what has not yet happened, for a future that has only been imagined, is one of the hallmarks of leadership.

That is the key challenge facing management today; change is the only constant.

Leaders are people who do the right thing; managers are people who do things right.

That's important to remember: it's not just a collection of great individuals but a group of people who enjoy playing in the sandbox, thoroughly enjoying collaborative problem solving.

The capacity for "uncontaminated wonder," ultimately, is what distinguishes the successful from the ordinary, the happily engaged players of whatever era from the chronically disappointed and malcontent. Therein lies a lesson for geeks, geezers, and the sea of people who fall in between.

The opposite of hope is despair, and when we despair, it is because we feel there are no choices.
