In regard to gambling, it's supposed to be fun and light because . . . well, you're going to lose most of the time. Maybe not at first, but it'll happen. It's designed to. Funny that you should mention game theory. I saw a guy I had been good friends with while growing up, not too long ago. His wife had just had a baby and it was the first time we'd really hung out for a while. I was surprised that he asked me to hang out and watch a football game with him, since I didn't remember him liking it at all. He explained later, that his interest was largely due to sports betting. He's always been a math guy and he approached sports gambling like a math guy: all stats, odds, theories and calculations. I have no problem with gambling. In fact, it's how I paid rent for the better part of a year when I was in my early 20's. The thing I have noticed with math guys who gamble, is that they tend to think that they have everything figured out and that they are almost always right. I have also noticed that these kinds of gamblers often are very dismissive of feel, which is how I gamble. My friend was explaining his process and his strategy and confided in me, ("this is not to be repeated to my wife") that he's had a 95% return since he started gambling, which was fairly recently. I know I can't convince him that this is bullshit, because in the 26 years I have known him, he has never been willing to say to my face that I am right about something. This of course, resulted in me punching him a lot when we were younger. Yes, gambling is numbers and it is odds but it's also luck. I know lots of people don't like luck because it smacks of fate, but luck in gambling most definitely exists. Why? Because there are too many variables to account for. Anyway, I liked this guy's attitude too. For me, the only money that's "mine" is the money I walk in with and the money I walk out with. Even then, it's not really mine either, but gambling money. I wish more people could understand that to be willing to win, people need to be willing to lose.Learning the game theory and how to play the long game was a lot of fun but the biggest thing I took away from it was definitely not to let short term loss affect you and realize how much risk you can afford.
