At that age I wanted to be a concert pianist when I grew up. I wanted to write books, too.

I think if I went back and told my 10-year-old self that being a grown-up would involve spending at least 7 hours a day sitting in front of computers moving meaningless bits of data around so that other grown-ups in suits could make money ... well, I think the best I could hope for would be that she wouldn't understand.
