Just linking this up here, an article about young Las Vegas juggler Ty Tojo (“Fifield”): stepson (and student) of the great Dick Franco.

What I find of particular note is the following quote:
“I’m proud of it,” Fifield said of his juggling skills. “But I don’t enjoy it. It’s a good career, though.”

He’s young. I remember Anthony Gatto saying about the same thing as that age.
As the father of a 9-year old boy I see how fast interests come and go. Some activities stick and some flow as fast as they came. It’s all part of the beauty of childhood.
I was at a seminar for how children learn recently and heard a speaker say, “Childhood isn’t supposed to be preparation for adulthood. It’s an era of its own.”
Loved that quote.
