How do you improve your self-control?

the so-called self-control means the ability to control yourself. Self-discipline is to be strict with yourself and have the ability of self-discipline, set a goal for yourself, or let yourself accomplish this goal in a period of time. For example, you are doing something now, and when you are halfway through it, you suddenly want to go out to play. At this time, you should have the ability of self-control, and you should be able to control your emotions and spirits without being distracted. A voice told me that I would not go until I finished it. A habit formed for a long time, self-discipline is self-discipline. Ask yourself.
