Lets say you have under $ 10,000, what are the first three things you would do in such a scenario? Would you just try to find stocks or investments that can double or triple your money? Would you get vaccinated right away? Would you look for other work-from-home opportunities? Would you take courses (which I've taken more than enough in life to feel like I'm going nowhere. Like I'm good with book knowledge but do not find it helpful when it comes to where the rubber hits the road)?
I've only read the OP and making this response. You haven't stated why you're not making money through Real Estate or Insurance, your eggs are in that basket so I can't advise with you painting half a picture.
I would not get vaccinated to travel, work or survive, you made a decision for a reason, so see that out to it's logical conclusion even if that's death (I'll never take it). Of course, if it's not that important go ahead get the poison and get a job.
Crypto is the obvious quick flip, but you need to dedicate time and research to it, and the market has been awful, nobody truly knows the market makers pulling the strings.
I bought narcotics in Cali and sold them in bulk in the UK, that's high risk medium reward. I realised I'm making good money through my business but the inner hoodrat in me wanted to do some hoodrat things. I don't advise crime.
Set up a cooking/food delivery business, take up a delivery job.
I don't know what your priorities are, if it's money then you can take any jobs, if it's a career, then giving you career advice at 45yo with limited background info is difficult.
