Let’s say a magical fairy hands you $10k each month…lol, that you may stop receiving after a few years. How could you build a business or invest that money so that it becomes a reliable income? And you have zero schooling, just starting from scratch. E-commerce? Buy a food truck? Day-trading? Real estate? What would you do if you were starting from zero and this is all you had? Sorry for the stupidity of this question!
I think that the best investment is to invest in yourself.
Git gud and you will earn more.
