Gambling actually ain't the problem here. Gambling is just a game where people get used to it. The real problem is the attitude of a person who is playing.
It is true. We cannot blame gambling games once we get addicted, there is no problem with those games. The problem is in ourselves, how we play & how we manage time + funds for gambling. The point is on those things, so if we can play normally, means know to limit time & funds during playing the games, then everything will be okay. In addition, control your emotions and expectation, realize that don't hope too much to be rich by gambling.
