I am summed up, somehow, by that.
I chose my professional school path in order to cause my father to lose a wager. I've always felt that makes me uniquely qualified to give career advice.
When I was eight years old, I won the statewide newspaper "What's My Line" contest. I supplied a caption to a cartoon. The cartoon pictured a very surly man behind a lunch counter, standing in front of a sign that said "Service with a Smile". My winning caption was "I haven't served you yet, have I?". I believe the prize was 5 dollars. That was the moment at which I knew that I was not a great novelist.
I'll bet everyone has similar "defining stories" of silly achievements. I'd love to hear any of yours.
