The only way I have ever heard of this is either through means of inventing and getting patents or by investing in stocks. If you're good at making things and have a good degree of creative thinking I would go with trying to invent something useful. If you have a friend or you yourself are knowledgable with stocks and numbers then that is also a very valid route. It is very risky though...I have heard of people investing great deals money in a company then the company does great for some time, but they hang on to their shares believing that they will continue to rise and then the stock plummets and they lose everything. It's very complicated and risky so I would advise researching as much as possible before attempting this. Another longshot is making it in any sort of media. Musicians, writers, and actors are a dime a dozen so the industry is pretty rough today, but hey it has to be someone who makes it. Why not you?
I hope this helped! God bless!
