YOLO is a good strategy if you ask me. I like your way of thinking. Personally, I do not believe in luck. The latter is commonly known because people do not want to assume their responsibilities. So if I got, for example, a bad mark on an exam, I would be like " I was unlucky."
Gambling does require decision making skills. It is not easy to make a wise and valid decision that you will not regret. It also requires internal skills that are related to making good strategies, and so on. And even if I lost, I would blame myself for losing because I made myself lose.
What is YOLO, by the way?
It seems to be an acronym for the "you only live once" phrase, but how it can be a strategy in gambling? Anyone care to explain? In respect to your other point about not believing in luck, I'm inclined to think that it is not a very wise approach in life at large. Indeed, you can't hope for luck all the time and still less rely on it, gambling aside, but you shouldn't discard it either. It is a possibility which is always there, and when it finally comes your way, you shouldn't think twice. Grab it and run! And don't look back!
