Ask HN: Looking for a career change from IT, where to start?

I feel burnt out and overall I don't really feel passionate about IT anymore. I'm looking to switch careers to a more people-centric job, like a salesman or real estate agent or similar, but I have absolutely no idea where to start, given that I have zero experience in the fields I'm targeting - I've only ever been a developer.

Anyone here did something similar? Any tips you can give me? Thanks.
