Never forget that you are one of a kind. And never forget, no matter how overwhelming lie's challenges and problems seem to be, that one person can make a difference In the world. In fact, it is always because of one person that all the changes that matter come about. SO BE THAT ONE PERSON." - Richard Buckminster Fuller. A leader is a change agent. It's not always enough to motivate others to act. It is sometimes necessary to be the one who does what needs to be done.
