Came across this exciting discussion, and I totally agree with you, in Nigeria there are numerous ways in which one can do to make money... first you have to know what you're good at, so many of our youth today are into content creating, blogging, trading, affiliate marketing, freelance, online campaigns etc... and it helps them financially, and there are also other skills that one can acquire in life to make earns.
But one major thing is avoid illegal stuffs to make earns, fraudulent activities, drug dealings and thief isn't a life for our current generation, make legal money and enjoy your life in peace and comfort...
