Being a late bloomer, I really didn't have any interest in children until my late 30s, but I'm so happy I didn't go through life without that experience.
I could have started a for-profit, venture-backed business that has a good spirit, and I think there are many of them - Google for instance. Maybe I could reach a billion people. That is high impact, but what happens in 50 years?
The sun stands for energy and youth, which is what I thought the circus should be about.
