I came across the original video of the dancing guy a while ago. But anyhow I did not think about it on the same terms as is described in this video. Because being a leader is clearly shown by the dancing guy here. Then you have someone else who joins in and then more and then even more.
To keep it short do not be afraid to stand alone while others are sitting down wondering what you are doing. Because you’ll eventually create a similar thing from the dancing guy here.
