I'm not so sure about the self-taught part. As long as you can demonstrate proficiency (assuming the rest is at least "OK", that is you have at least a school certificate!), you should still be able to get hired, even if you're auto-didact. Surely not in the same salary class as someone with a university grade, but a no-suck job should certainly be attainable. Assuming your skills are what they need, and assuming you are comfortable in demonstrating that you have them.
leaving school early and returning on your own terms later or never returning at all
being self-made and self taught which doesn't necessarily work in other countries as a viable life path
About dropping out of school, you are most certainly right. "Dropped out of school" will absolutely not work, this is not a valid consideration.
Problem in places like India is you have 1.2 billion people of which a few thousand are extremely rich even compared to western standards, a million or two are extremely rich by Indian standards, and the remaining 1.99 billion are poor, no matter who you compared them against. A considerable part of these 1.99 billion leads a life which is not just "poor" but quite undesirable in every respect. Maybe you have seen one of these features on TV where 8-10 year old children defecate on a public place and more or less live off the garbage dump (which is on that public place, too). Poverty was kinda bad (but not so extreme) when I last visited India about 30 years ago, but their population has nearly doubled since then. So it's easy to tell that what you can see on TV is not much exaggerated.
Still, compared to the ones who have to work in the stone quarry, or compared to the ones who are abducted for organs, the kids living on the garbage dump have a pretty good life.
Everybody wants to get out of that, no surprise there.
So, unlike in other places (USA/Europe) where it's enough to be in the top-10% to get a reasonably well paid job, and in the top-5% to get a well-paid prestige job, you must be in the top-0.01% to succeed. That's simply because there's just so many more people trying to get out.
Unluckily, I can't tell a magic formula for landing in the top-0.01% (other than the obvious of being gifted, and working, working, working). I've only ever gone by "the good horse will not jump higher than it needs to", and that worked well. But I'm not in India...
Going to school at all (and finishing) even if you don't manage to be the best of the best is a good start in any case. Finishing at all more or less means being in the top-20% already, no matter how you do -- as long as you finish at all. And if you work hard, you will likely manage at least to get in the top-10%. Which means you are maybe not getting your dream job, but at least you don't have to work like an animal in a job that breaks you.
You mean remaining 0.99 billion
