Servant leadership teaches us that you have to lay your cards on the table.

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."

Expect the best from your people and they will usually deliver but your expectations must be realistic.

Good leaders make people feel that they're at the very heart of things, not at the periphery.

Embrace error: Create an atmosphere in which prudent risk taking is strongly encouraged.

Without a terrific leader, you're not going to have a Great Group. But it is also true that you're not going to have a great leader without a Great Group.

Great leaders love talent and know where to find it. They surround themselves with talented people who can work effectively together.
