There can be leading in following, too. By following, you give other people a chance to lead. When other people in your team have a chance to lead, the team benefits. Most obvious is the opportunity for them to learn, which expands your teams leadership capacity and thereby its ability to deal with multiple priorities. Not only do they learn about leading, they also get a better sense of what is important to the project. Additionally, when other people lead, it gives them a better sense of ownership in the project. There is no better way to engage them in the vision than letting them take the reins on advancing it.
