I recently read that 90% of the working public believe that they are in the top 10% of best employees.
Which means about 80% of the population (or more!) think they're stellar overachievers but are wrong. Are you one of them? =)
At Pizza Hut.... I worked with a large number of very incompetent people and have little doubt I'd be in the top ten percent. My days at Intel.... Oh, I'm smart, but frankly, the job bored me and it probably affected my performance. I doubt very much I was one of the top 10% of their top employees. Fortunately, I'm pretty sure I wasn't in the bottom 10% either which is the place you really want to avoid. I have no qualms about being average. In fact, most people are. That's the definition of average, you know. ;o)
I like to think I do pretty well, but I'm not fooling myself. Deep down inside, I really am average.
