If most people are "sheeple", how is it that each of us has avoided being one?

Is a feature of being “sheeple” a self-awareness of being one? In other words, do “sheeple” know that they are one of those mindless sheep that are simply following the herd? Or do they think of themselves as having valid reasons for their beliefs and actions?

If each of us cannot be lumped into the term “sheeple”, is this because we were able to self-diagnose ourselves? “Hmm…let me see…Nope! I’m not one of those ‘sheeple’. Good for me!”

Why are we so lucky? What are the features of “sheeple” that we don’t have? Are we not human?
