"Great leaders create movements by empowering the tribe to communicate. They establish the foundation for people to make connections, as opposed to commanding people to follow them."
from Tribes, p. 24
The above sounds very simple and straightforward. But I've got a feeling that communication is considered more a hassle than a benefit at your office, in your school, around the dinner table or as part of your congregation.
Of course, the closer you are to each other, the less you need to shout.
But that's also easier said than done.
