I was just putting my six year-old son to bed, I had sang him a song and was idly chatting him to calmness. Somehow, the conversation turned to homework and then to money and then to the kinds of jobs people can get, relative to the amount of homework they get done.
“You could be a doctor, a scientist, even maybe work with computers, like me”, I hinted.
“Is that possible?”, he asked.
Trying to wrap the conversation up and get him to go to sleep I looked him deep in the eyes and tried to impart the noblest of fatherly advice, the bedrock of my worldview;
“Anything is possible, son”, I said.
“You can’t bite you own butt”, he replied.
At that moment, I was enlightened.
