I love this video. In the beginning there are always going to be many people who are willing to follow you as you try to accomplish something (or in the case of the video go on a journey). On the way to attaining your goals you may meet even more people willing to follow you. But after a while the crowds will dwindle, and all those people will stop following you. The only people left will be the leaders (in the case of the video the 2 leaders of the group). Only those who follow their own path will follow it all the way to the end. The true meaning of the song: Be your own leader in life. follow no one else or you will be left behind.
