Should I move to Hawaii or stay in California?

I am thinking about moving to big island Hawaii. I am thinking about attending Hawaii Community College and living in the Dorms at University of Hawaii at Hilo. ( You can do that, they share facilities) Anyway, I would be living behind my brother and family ( who I dont really talk to anway) and it would be a risk and unfamiliar to me but so many kids do this all the time right? Kids who go off to college in another state?
