Always win or always lose, winner or loser, Gambling is addictive game that can affect anyone. No matter you always win or always lose, if you play in a long time, you get addicted. When you win kept playing and eventually difficult to be separated. When you lose you continue to play out of curiosity, to finally win and want to win again until the addiction.
I don't think this applies to everyone though. I've been gambling for a long time already and i don't feel the urge to continue gambling and waste a lot of my time doing it. Addiction comes to those people who i think, doesn't know how to determine which things they should prioritize. People who get lost when they're enjoying what they're doing. Not all people are like that though.
I think so too. What experience as taught me is that gambling is not something to make a living out of. You'll just go broke in the next few hours trying to become rich from gambling. Then after that you'll get addicted to it, because you will always think that you will get back your loses. In the end you just lose more money. Gambling activities should be kept to a minimum, that is my rule.
