I checked out his biography. Here’s one tidbit:
Pacino went to the High School of Performing Arts in NYC & flunked nearly all of his classes except English & dropped out of school at 17. He started smoking at age nine. He has 3 children and never married.
One thing about actors/actress.. some go the route: Jodie Foster/Natalie Portman of schooling, prep, structured life
some go the route of fly by the seat of your pants
both can & do succeed.
