As someone whose done it, I can tell you that you shouldn't rely on making money over the long run at poker. There are a lot of reasons why you'll probably fail, no matter how smart and hard working you are, most of them emotional. It is a great way to learn decision making with incomplete information though. There's sort of a class divide in the world between those who understand and apply the concept of expected value to every part of their life and those who don't.
