17 is a weird age but ymmv. I left home at 16 alone to study abroad. I had tons of free time due to dorm curfews and such. Unfortunately, I was too poor to have a computer and the computers we had access to were completely locked up. (Naturally we waltzed past the locks to play some games but it was also under surveillance)

Paradoxically I coded way more between ages 12-14, I regret my wasted late teens.
