I can definitely agree with your "hobby" statement!
My son has been into skateboarding for a few years now.
He wants to be a pro, but that's like wanting to be a pro anything,
there are very few slots open.
You have to be exceptional, or exceptionally lucky.
He IS lucky.
I'm starting to think we should help him try to find a sponsor.
Sending him to school would be like putting money in the fire.
