True, it's almost the same as the function of a project manager. The project never defines his purpose or function or calling as a project manager or leader in this instance. So also will true leaders find themselves involved in 'projects' that may have nothing to do with their personal purpose. Their calling as a leader however and their own character traits is what will set them apart as a leader in all circumstances.

Leaders will find themselves in a position where they are purposed to salvage someone else's bad 'project'. :)
