The thing is simple and I think most successful investors know this as well that you don't have to invest on stuff you don't know. The most basic one. Of course it's not for everyone just like other type of investment or job or business that may opportunely be on your way.

Even if you learned something or doesn't that greedy it doesn't mean success is on your side, there are other factors to consider just because you learn, there may be other thing along the way that will challenge your faith on investment.
