Shorting your play time in gambling is the best strategy in gambling, apart from knowing how to manage your bankroll, don't spend too much time on a casino game, the longer the time you spent the more you lose, this is the truth that many gamblers won't accept at first until they realize it later.
For them it's about your addiction, and that's what brings in more money, and I am here to announce to you that time fixation is also a good way in gambling, spending 20 minutes in casino a day is better than someone who spend 1 hour.
Although your suggestion is Wright, but sometimes our emotions plays a big role in our lives. If you can't control your emotion you can't control your time. Because when ever your emotion I'd working time has nothing to do. Although the time and emotion works together but I think it's your emotion that control the time because there will be a point in time when you loss more often and you choose to continue until you win without considering the time countdown and it will definitely affect you.
