I used to work full time in a downtown office.
It was a pretty fancy job--I mean, it was a cubicle, but I made fairly serious money, and I had a long title, and people worked for me. I dressed nice and made reports, and talked rich people into giving me money (I guess I still kinda do that).
And then one day, out of a clear bright sky, the world changed.
The day after, September 12, 2001, I looked at a sign posted on the wall of that cubicle. It said "I'd rather be figure skating."
And 3 months later I walked out of that cubicle and into an ice rink as figure skating professional.
