One thing you should be aware of, though, is that Southern California is a completely different universe from Northern California
When my wife informed me in 1986, that she wasn't happy in the bay area, (We lived in beautiful Marin County) and that she wanted to try moving back home to L.A. I was faced with a problem. If I refuse, as was my inclination, then whe would likely resent me for all time. If I agreed, then I would have to live in L.A. (Nooooooooooo!!!!!!) So I formulated this secret plan, I would move, suffer for a year, then insist on returning to the Glory of the San Francisco Bay area. (I really do love it up there.)
That was 1986, I've been in L.A. ever since, and will likely die here, hopefully in another 40 or 50 years.........
The block where I live, about 3 miles from the ocean, has the best weather, IN THE ENTIRE WORLD, yep, my block. Theater, music, used instrument stores, beaches, mountains, deserts, food, food, and better food. Many fine people, and the stereotypes are a source of everyday comedy.
I would posit that L.A. is like many large Urban areas in the world, whether you are happy or miserable here, depends more on what you bring to it, than the inherent nature of the place.
I LOVE L.A. YMMV
