Move out at 18, and have a happy life?

my dad wants proof of people that did infact, move out of their parents’ home at 18, provide for themselves, and then end up having a life they were happy with.
he’s concerned for me, and i do honestly love him and trust him, but he’s concerned i won’t ever finish college and that i’ll become a junkie cleaning toilets for extra money, unhappy with my carrer. i am an artists, i make money and enjoy doing it very much. i’ve already found a few music artists, and a couple of sculptors, but it’s be cool to find, i don’t know, like a few political or business people? any inspiring people you can think of, any stories you like?
