Here's an interesting idea: You could become a "Financial Free Trader". This is an alternative to the free money tree.
The first key difference is that you're free to do more or less what ever you want to do with your cash. If you want to invest it, invest it. If you're running a business, run it. If you just live on what you can earn with no intention of earning much more it's fine. You just don't have to.
The Free Trader concept allows you to do that and be an independent investor. It's not too hard. It's the same free money tree story. But with much more room in which to work with.
Why should you go into this? Well first things first, you want to be comfortable with what you do. Do you go into the stock market? The music business? The fishing industry or the fashion industry? If you are new to any of that, be prepared for uncertainty.
