People who score lowest in skill rankings tend to overestimate their abilities

"Ignorance more frequently begets confidence than does knowledge."

Thank goodness for ignorance! Goes right along the lines of "if I wasn't naive enough to know what I was getting myself into then I would have never started."

Another quote...

Later studies go on to cite a survey that found that 94% of professors ranked their performance as "above average" when compared to their colleagues.3 It does not take a degree in mathematics to notice a problem with that figure. Speaking of statistical impossibilities, multiple studies have determined that the vast majority of us "average people" consider ourselves to be well "above average."4

That's good, not only do I suck, but the majority of the people around me suck also.

I suppose this means that the majority of people are confident that they are highly skilled and perhaps as a result don't work terribly hard to improve those skills. Work harder at improvement then you can likely make some great progress relative to your peers.
