Life in Trivandrum, from someone who actually knows what’s what?

Hi people, I’m considering moving to Trivandrum. Having lived abroad for a while I am thinking of making the move back to India (originally from north India- pls no hate lol). In my experience, everyone I know from Kerala wants to eventually settle down there. But for someone in their 20s or 30s, is it worth living there- how’s the social life, salaries (I have my own dental practice, I realise it’d be lower than cities like Bangalore or Pune, can’t say for sure). What with all the talk about the port, I think it will see a boom in the next decade or so, and it would be a great opportunity. I just don’t want to spend my “youth” in search for peace and lose out on getting making the most out of life in general. From what I understand about Kerala (Trivandrum, even Kochi is an option) it’s clean, safe, affordable, and progressive (by India’s standards)- tho I want a real life opinion on this. As for language, do you think I can get away with English to start with, I’ll obviously learn Malayalam, i can say the “ñ” sound in njam, and can almost say “Vizhinjam”, so I’m almost fluent.
