“People generally fall into one of three groups: the few who make things happen, the many who watch things happen, and the overwhelming majority who have no notion of what happens. Every person is either a creator of fact or a creature of circumstance. He either puts color into his environment, or, like a chameleon, takes color from his environment.”

“There are generally three kinds of people in the world. People who make things happen, people who watch things happen, and people who say, what in the heck happened.”

“There are three types of people in this world: those who make things happen, those who watch things happen, and those who wonder what happened.”

“There are really only three types of people: those who make things happen, those who watch things happen, and those who say, What happened?”

“There are three types of people in this world. Firstly, there are people who make things happen. Then there are people who watch things happen. Lastly, there are people who ask, what happened? Which do you want to be?”

“There are those who make things happen, there are those who watch things happen and there are those who say 'what happened?”
