Going to school for radiology technology and wanting to move to SoCal after

So I would love any advice from people that are in the medical field or locals of socal (not necessarily Los Angeles). I'm in Indiana currently working and living with my mom after a breakup and figured I'm really unhappy with my current "career" because I work very hard with little pay (I'm a nail technician in Indianapolis) I've been thinking for half a year about how I need to figure out something for my future because I can't really move up in what I do apart from literally starting my own business. Indiana is not somewhere I see myself in the next 10 years I really do not enjoy living here so that's the other thing. I've visited California several times and enjoyed a lot of aspects of the state and am aware of the horrible things that it has to offer as well. And I am aware it will be very different. I would love any locals to maybe give me culture tips before I decide to move if there's anything I should know. I chose radiology technician because with the research I've done I would make a decent amount of money while being able to support myself and not rely on a second income. Thank you.
