Replying to Thinking about moving to Cali

Just recently took a trip out to Orange County/LA area for work and it was insane. I'm currently living in Boston and studied in Colorado but looking to change it up and Cali seems like a dope spot. What's a good place to move that has jobs (ideally it'd be close to a city), somewhat close to the ocean and close to mountains?

I've only been to Cali for two days so I'm pretty clueless when it comes to the state. I'm 25 and do video production for work if that helps!
