Harrison's father is on the money. When I was in college pulling out all stops to get As, friends warned me that it was the C students who wind up being the bosses of the A students. Research confirms that.
There's not a lot of payoff, at least long term, in being an A student. While I was ensuring that I was prepared to give professors the answers they wanted, I could have been freelance writing for newspapers and magazines. That didn't happen until I was 33 years old. I traded off the risk of rejection for the certainty of getting As.
Also, as we all know, C students are developing social and even leadership skills with the time they don't invest in getting As. It wasn't until I read Dan Goleman's book on emotional intelligence in the mid 1990s that I recognized that I didn't have it. Moreover, as one who continued to live in my head, I didn't acquire EI until 2003. My business had a meltdown. I had to get along in order to rebuild it.
In addition, As aren't like financial investments. There's no chance in hell that their value will appreciate. Actually, like a new car coming off a lot, they quickly lose value once one leaves formal education.
My fantasy is returning to college as a C student.
