I can only speak for myself, but public school did nothing for me musically. I got the impression a musical career was frowned upon. But in the arts, resistance can often be the strongest inspiration.
The passion of the Italian or the Italian-American population is endless for food and lore and everything about it.
I came from a poor family, so working and going to school at the same time was natural. It taught me multi-tasking, although we didn't call it that back then. I learned I could never be idle, I need to be doing many things at once.
