I lived half my life in San Diego, and they were exceptionally good years. I was very active and outdoorsy and had the discretionary income to travel.
If you’re athletic/outdoorsy, there aren’t a lot of places – IMHO – in the world that are a whole lot better than CA – hiking, climbing, skiing, Scuba, road cycling, mountain biking, motorcycling, backpacking/camping, and on and on.
And CA really is … everything. You can pick a CA that you like – it’s almost surely there. The cost of living and the traffic/pace/rat-race of the larger urban centers gets/got tedious but it’s not hard to eschew those hellscapes for many.
If you can work remotely, or simply live where you want, there are charming exurban or pretty rural communities that – dropped into them by helicopter at night – you’d never know you were in CA.
The state has some 40 million residents, making it very hard to paint them all with any kind of a broad brush. It’s America. It’s not rural Mississippi or Brahmin New England, but there are so many people from somewhere other than California that the cheap and easy labels really don’t hold up to much scrutiny, fun as they are to offer up 
And I loved the Latino culture, and I miss the hell out of the Mexican food – the exquisite white linen, fine dining places and – especially – the burrito joints. Oh, man, oh, man…
I’m glad I lived there when I was younger and ridiculously active. The people I met who grew up there used to just gush about SoCal in the 1950’s. I’d have liked to experience that.
But you know the place you know, and then you get to watch it all go to hell.
And – as somebody with a passion for travel – whenever somebody in CA would ask me where they should go first, my answer was always the same: you’re already here. California is vast and complicated and intricate and beautiful and rugged and as diverse as all get-out.
Until it falls into the ocean that is. I’ll definitely miss my mother. She’s only a couple hundred yards away
