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

The leader...is rarely the brightest person in the group. Rather they have extraordinary taste, which makes them more curators than creators. They are appreciators of talent and nurturers of talent and they have the ability to recognize valuable ideas.

The learning person looks forward to failure or mistakes. The worst problem in leadership is basically early success.

Almost without exception, members of great groups see themselves as winning underdogs, as a feisty David hurling fresh ideas at a big, backward-looking Goliath. They always have an "enemy."

I used to think that running an organization was equivalent to conducting a symphony orchestra. But I don't think that's quite it; it's more like jazz. There is more improvisation.

Around the world, the generals are being ousted, and the poets are taking charge.

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