I think you need to control yourself in gambling and being discipline about your strategy, how you play and how well you calculated the winning odds could make your strategy works better, luck can't be rely on in gambling, you need to build strategy to win based on your experience, and strategy is only to help you prevent losing money not to add your winning percentage
Agree because discipline will make you have good control and always try to play safely, which means you don't have to bet the same way repeatedly and at that time strategy and experience will be a main priority, because there is a time for you to bet big with big odds when you see and feel the opportunity is indeed very good and vice versa. Make every bet you do to be as comfortable as possible so you can have a good mood when betting.
