I agree! Youtube is a cheap way to get started (phone) and it has unlimited upside. What do you like to do for fun? For example, if you are obsessed with drawing cartoons, tasting different types of alcohol, cooking, gaming, learning about finance, etc... there will be an audience out there for you. You will learn marketing, research, content development, and sales with little risk.Can I suggest starting a business - or at least trying. Even if you fail - 5k down is an education in itself. You would get more value from 5k starting a business - than most MBAs. 5k is not too much to lose - but could teach you so much
In the world of successful people, most are self-made. If you start something you have full control over how that money is utilized versus putting it in a stock and hoping 1) Management doesn't screw it up 2) There's a downturn in the economy 3) There's a downturn in that specific sector 4) Competitors swallow it up, etc.
If nothing else, it can serve as a side hustle until it becomes your main hustle. There are few things better than the feeling of getting paid for value you provided for someone else.
