This may be more about our individual perspectives. Gamblers who crave winning won't easily abandon gambling when they win, and even when they lose, they'll likely be tempted to continue gambling, hoping to turn things around. Even if they've already won and perhaps achieved their desired goal, I suspect the urge to continue gambling will still be there, especially since I personally find gambling more comfortable at night. Unlike those who view gambling as entertainment, whether they win or lose, it's easier for them to simply quit and abandon gambling.
