People buy into the leader before they buy into the vision. Many people who approach the area of vision in leadership have it backwards. They believe that if the cause is good enough, people will automatically buy in and follow. But that's not how leadership works. People don't follow worthy causes; they follow worthy leaders with a cause they can believe in. They buy into the leader first.
