There are 3 kinds of people in this world:

those who make things happen,
those who watch things happen, and those who wonder what the hell just happened?!"

And you missed out one, those who spoil things

everybody participates in whatever happens. The whole world works as a team. Some people give the lead and others follow. Hence basically there are two kinds of people- leaders and followers. Simply watchers and onlookers are few and negligible.
