is to start with people who want what you want.
Identify, organize and excite people who are already predisposed to achieve what you had in mind and you're much more likely to have the outcome you seek. It's far easier (but less compelling) than turning strangers or enemies into customers/voters/supporters/colleagues. Over time, an engaged and motivated base of followers is the single best way to earn more followers.
You used to be stuck with whoever walked in the door or opened your mail. Today, you change minds indirectly, by building a tribe that influences via connections to others.
