Some project in which you must organize and delegate duties to many groups of people. Randomly try to get a group of people to do something that they normally would not do out of laziness. Give a speech to persuade a group of people to act in a certain way. As you may find from doing these, each takes many different skills to be successful. The more well-balanced the leader, the better.
Leadership revolves around people.
You must understand the people you are trying to lead. Get to know them. You can't motivate anyone to do something you don't believe needs to be done. If you want to lead the orchestra, you have to turn your back to the crowd. You have your own leadership abilities.
