The statistic from Paul Graham reminds me of a time when I tried to bring my grade in a mathematical computer science course up during exam inspection. I explained to the very formal (mathematical formal; he was also friendly) that I should have gotten half the points for one of the questions because I got it partially right. Without much thinking, he responded with "No. It’s wrong." It has been a great life lesson for me. You can come up with all kinds of nice stories about how right you are but sometimes you’re just wrong.
