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!
The thing is it depends so much on you. I loved owning real estate but for many dealing with the hassles sucks. I have a cousin who is Harvard educated - for him what I did was chump change.
I think you need to inventory your strengths and tolerances and design a plan that works for you.
A previous poster recommended education - finding a mentor who has done what you want to do might be the best practical advise given.
